Save Xmlhttprequest - Small Gadget Which Downloads A Series Of Images From Web - Displays Images In A Loop
May 25, 2010
I am working on a small gadget which downloads a series of images from the web and displays the images in a loop. However i am having trouble saving the xmlhttprequest to a file to use later in an array. I have read that it should be easy to save the .png using Scripting.filesystemobject but have been unable to find any information on how to do it.
Here is my code so far:

I´ve just launch my website-portfolio, well it´s not yet the final version but it is almost and despite I am satisfied with the final result I´ve detected a really strange bug that only happens sometimes. The thing is when the first introduction Slide appears (the one with the hand-made drawings), sometimes the images shrink from the normal size to small tiny images. This doesn´t happen always and if you refresh the page it disappears.
Follow the link to the page were the bug happens - [url]. I'm using jquery cycle plugin, check it out.

I need to display a set of images. NOT a slideshow that automatically changes, but a very simple display, one image at a time, that moves to next or previous by mouse click or arrow.
I can retrieve the set of filespecs in php with no problem. And I've got the setup in php to display the file, one at a time.
I"ve figured out how to open a full-screen window in javascript.
What I need (I started in php and they sent me over here for specific javascript info), is to put everything together...
1. I'd LIKE to automatically set the resolution on the system to 1024x768. I've been told html and javascript can't do that, so it'll have to be done by the user.
2. I figured out how to open a full-screen window in javascript.
3. What I need is to display the image from php and have it show up in the full-screen window I created. Then it just sits there until the user presses an arrow key (or hopefully something with the mouse) to go to the next (or previous) image. Back to php for the next file and display...
Once the last image in the set is displayed I'd like to have the window I created go away, sending me back to the screen from which all that got started...
So, as far as I know, the two things I need to know are how to display an image in a particular window from php. And, how to get mouse-clicks and/or arrow keys back to php so I can use them....

I need to have a series of images cycle in the background, and for each image, text should appear on the right or left side and slide into position. I thought this would be simple but can't really find any information about how to connect these two events. I've done plenty of background image cycling, but never tied a particular image to a particular animated effect. One, can this be done...if so, how challenging is this? And Two, would anyone know of a location of similar stuff. I've seen a bunch of sites that use Flash for this, but it seems like jQuery would be quicker and more robust.

I created a slideshow that displays the 5 images randomly. It is for a college project for a class I am in.
Here is the HTML for the area that holds the images
And here is the external .js file for it
I had the slideshow working completely fine... then when i finished the rest of the site and added more pages, it is now not working for me. It just sits at the original image that is loaded when they site loads.

How to auto-align and distribute many small images inside a div ?
I want something like that :
<div class="ContainerThatAlignMyIcons">
<img src="img1.jpg" width="10" height="10" alt="img1" />

I want that jQuery distribute all this item for the left border to the right border of the div.
I wonder if any plugins is doing this ? I did a search in Google and I do not find something near the result that I want.

I'm working on a project that involves a page with a large amount of images (sometimes 400+). What's the best way to handle this? Should I track the loading-state of all of them, or is it save to assume I can do stuff as soon as the last image is loaded? So.

I found this perfect javascript for creating dynamic connected drop down boxes. This script works fine but there is just one thing I want to add but unfortunately I'm not familiar with javascript enough... I want to display small images when an item is selected from the second drop down. An image should be assigned somehow to each selection from the right hand drop down menu in the code and when someone selects something from the list, an image should be displayed next to it automatically.

I have a listings page which displays results using images and text which are stored in a MySQL database, all is working fine. The images are pulled into the page from the database and each listing can have up to a maximum of 10 images. Some will have all 10, some probably one or two, so the page is coded such that if there's an image in the field, it displays a thumbnail, if there isn't then it shoves a "Â " in instead.
The results page has one main photo (image 1) and then a series of thumbnails (images 2-10) below it and I need to be able to set this up so that when someone clicks on image 2 it shows the full-size version of that image in the div where image1 sits, and the same for however many remaining images there are.
So my question is, how easy it is to do this with javascript and does anyone have any idea how to code it?
The main photo sits in a div whose id is "mainphoto" the remainder all sit in a div whose id is "thumbpix".

I wish to give the user the ability to download a file. The variable "url" is set to the url of a file on the server. I want to give the user the ability to either open it (if known type) or save it.
The following works for documents such as MS Word, but not for images (jpg, etc):
window.open(url,'Download');
Any suggestions how to not just create a new window for images, but give the choice whether to save it or view it?

I know that there are some really nice jQuery UI. However, I'm really new to jQuery and I need to save the order into a SQL Server database so that next time if the same user comes back to the site, the picture will be in the same order that he/she reordered it previously.

I have recently worked on a flash based learning course and built functionality where users throughout the course can type in their own notes based on the course, and they can revisit these everytime they launch the course, the functionality is simply using flash cookies to store the notes on the users machine. I wanted to build functionality so that they could then save these notes to their hard disk and e-mail them on. To do this I call a javascript function from flash which opens a new webpage, passes through the notes from flash and uses document.write to write the notes to the new webpage. Then the user Saves (as web page html only) to save a copy to their machine.
The problem is I want to do this web page up a bit more, add graphics etc. but if I save as web page html only it won't include any images I add to the html page, and if I change it so that they save as (Web Page Complete) rather than write the webpage out with the notes it will write the webpage with the code document.write(string) but as this is on the users hard disk now string will be undefined as it no longer run alongside the course. Is their any other way anyone can think of doing this type of functionality, I am trying to stay away from using PHP

I think to preload an image I should us something like:
img = new Image();
img.src = 'images/img.jpg'
Could someone tell me how to create a loop which would preload a list
of images? Something like:
ImagesFolder = '...'
ImagesNames = '...'
For i = 0 to ImagesNames.Count
img = new Image();
img.src = imagesFolder + imagesNames(i)
End
Is this a good approach? Could someone tell me the javascript code for this?

Let's say I have a Javascript function that loops over and over. In
that function i have it alternating images on a button this way:
if(var==0){
var myHTML = "<input type='button' style='background-image:
url(grnbutt.jpg);etc. etc.'>";
var outq = document.getElementById("qbutt");
outq.innerHTML = myHTML;
}
else{
var myHTML = "<input type='button' style='background-image:
url(grnbuttdark.jpg);etc. etc.'>";
var outq = document.getElementById("qbutt");
outq.innerHTML = myHTML;
}
This works great using Firefox, and works with Internet Explorer also
EXCEPT if its set to "Check for newer versions of stored pages: Every
visit to the page". With that setting, IE will download those 2 images
from the server every single time through the loop. So then I tried
putting both images on the same jpg and then moving the image:
if(var==0){
var elem = document.getElementById("grn");
elem.style.backgroundPosition = "-100px 0";
}
else{
var elem = document.getElementById("grn");
elem.style.backgroundPosition = "center";
}
This also works, but also, constantly downloads new images when using
IE with the above setting. Microsoft calls this a "feature". They then
offer a fix for this "feature" that... doesn't work. Preloading
doesn't work. Loading the 2 images in a <divset to invisible doesn't
work. I've tried suggestions of creating php files that tell the
browser that the images don't expire for years. That didn't work for
me. Many people have also suggested that there is no way around it...
it can't be fixed until Microsoft fixes it.
So, is there any javascript way to loop 2 images on a button, without
Internet Explorer constantly downloading those 2 images over and over,
when its set to "Check for newer versions of stored pages: Every visit
to the page"?

i am making a gallery and i was advised by philip m to preload my images before hand, so that the gallery runs smooth. i have done so but in a different way to what ive seen on some of the other posts on this forum and i was just wondering if this was practical javascript or am i over doing it.bascially, the images are external hrefs loaded into place holders.the external hrefs are stored as strings in an array.
so the loop runs for however many image hrefs are in the array.so the first iteration of the loop, an image is created and is given the href of whateever value the loop is of the array.then for each iteration of the loop, the var img, is overwritten with the next href in the array.so technically, iam not creating as many images as there are in the array, i am just creating 1 then overwriting it, but still loading the image data in to the browser cache.

I am trying to do the following: I have written a simple programm that loops through an array of images when the user clicks a button. I have used a for loop to do this. The program works fine, however when I get to the end of the array, the condition created in the for loop is "true" therefore the button no longer changes the image. How do I start the loop again to create an infinite loop (i.e. every time the button is clicked, the image will change)?The script I have written is as follows:
var mySpheres=new Array("sphere.gif","sphere2.gif");
function changeSphere(){
mySphere=document.getElementById("sphere");[code]....

I'm designing a page to fade multiple images (three) in and out over a set period of time (one minute, say). The code I have works as follows:
I define an array and fill it with the div objects I want to fade in and out. I have some simple tags (2 for opaque, 1 for fading in, -1 for fading out, etc.) that I set to show the state of the object.
First I check if the object is opaque, and if so set it to fade along with a time;
Or if it's transparent I give it a 1 in 10 chance of fading in during this iteration. If it's currently fading in or out I check to make sure it's on track and change the opacity of the div accordingly.
Originally, I had the function call back to itself using setTimeout after the loop had gone through all the divs and changed their opacities appropriately. This caused an out of memory error (though, strangely, if I had any alerts in the function it didn't give me the error).
So the version below has the code in a while loop to let it run for 20 seconds - this gives me the "a script...run slowly, do you want to continue the script?" message.
So I have several questions:
1) First and foremost, why is my function causing out of memory/run slowly errors and what is the best way to fix that?
2) Is there a better way to code this effect (final result will be six lights fading in and out for a minute or so).
3)I'm not an experienced programmer, so any bad practices, ways to streamline, no no's, etc. that you see, please point out.
I've only posted the script here - the page simple consists of three divs (id's grad0, grad1, grad2) and a call to the function copied here.

I want to create a javascript function which preloads a few images.
The function preloadImages should receive a variable which indicates the web site current culture.
If culture = "pt-PT" then should use arrayptPT
If culture = "en-GB" then should use arrayenGB
and so on...
Then all images of the array should be loaded using a For loop.
All the images in the array are in path: images/ culture value /.
So the ideal would be to have only the image filenames in the arrays.
Then the loop would go throught the right culture array and load all the images there from folder images/ culture value /...

As it is known from the title, I'm building a web page running continuous slideshow of images, like watching a video. I wrote the header part below:
Quote:
<script language="javascript" type="text/javascript">
var slideimages = new Array()
function slideshowimages()
{
[Code]....
Here, the biggest problem is, when the page is loaded there are still coming images saved from a capture device. So, my images from the captures device can not be loaded to my web page. I need to pass these images directly to the web page as real-time video taken directly to the web page.

I need a JavaScript (or something else) that will fade out the web site, on load, and display a series of images, then display a "Continue" button to go back to the web site. I have an idea for a cute (and funny) way to get people interested in my site that has a weird name. I searched high and low (Google!, amongst others) for anything that would be close to what I need, to no avail.

I've put together a function for screen scraping, just to see if I could do it. Basically, this gets a stock quote from Yahoo! and displays it. It works with no issues in IE7. FF and Chrome, however, it does not work. It will not display anything. Error Console is not returning any errors, and I'm a total novice when it comes to troubleshooting with FireBug.

I'm sure it's something simple, something I've overlooked. I'm beginning to think it might be with the trenary conditional setting the method.
