Does anyone have a code snippet that would preload and entire directory (and sub-directories)?
I'm using a basic JS array to load individual images but was hoping I could find a more scaleable/efficient way of doing it?
var yourImages = new Array("images/1.jpg", "images/2.jpg")
I have some images 5 or 6 that are 800 x 300 i use in my website banner.The start loading but when number one is 1/3 of the way teh next one starts then the next, it looks real messy nee some way to preload them ... like black square or something .code i used below
<script language="JavaScript">
// configuration structure
var A_TPL = {[code].....
I have this working fine, and I can append the preloaded image to a hidden div then fade the div in for a smooth effect.
Problem is I want to set this preloaded image as a css background image, not as a <img /> in a container. But if when the image is loaded, instead of .prepend() I do .css() and set the css property of a background-image to be the preloaded images URL, then when it carries on with displaying it the browser loads the image again. Rather than using the preloaded one.
I want the image to be a background image as I want it centered in the page background, even if it is too large for the viewport.
I got a script that rotates my images, but I have almost 300 in stock and it is preloading all 300 once the script is started. How do I get it to preload one at a time, or nothing at all? Code:
View 3 Replies View RelatedMy question is can I use home page preload some images which will not be used for this page, but will be (potentially) used for later pages?
My problem is the home page does not have any images at all, I use following code in head section:
<script language="javascript>
img0 = new Image();
img1 = new Image();
img2 = new Image();
img3 = new Image();
img4 = new Image();
img5 = new Image();
img0.src = "./images/arrowUp.gif";
img1.src = "./images/arrowUp.gif";
img2.src = "./images/track.gif";
img3.src = "./images/drag.gif";
img4.src = "./images/arrowDown.gif";
img5.src = "./images/bottom.gif";
</script>
This cause the home page display nothing.
Any ideas or thought?
This isn't working and I can't figure out what I'm doing wrong:
var c_imgs = new Array(
'images/champascari.jpg',
'images/champfangio.jpg',
'images/champhawthorn.jpg',
'images/champhill.jpg',
'images/champsurtees.jpg',
'images/champlauda.jpg',
'images/champschumacher.jpg');
var pre_img;
for (var i = 0; i < c_imgs.length; i++)
{
pre_img[i] = new Image();
pre_img[i].src = c_imgs[i];
}
If this code is correct, should I put it in a function and then call for
it ?
I trying to:
- preload an image
- then call it as a a background image.
But cant get it to work- here is my code...
I want to use an image as a CSS background-image so I used the Image constructor to load the image: [URL] but I noticed that the browser (Firefox) load the image from the URL and not from the memory when changing the background-image property (it takes about 1.5 seconds before showing the image, and every time I reload the page!)

// preload images
tipTransparentImage = new Image();
tipTransparentImage.src = 'images/bg.png'
tipTransparentBgImage = new Image();
tipTransparentBgImage.src = 'images/bgs.png'
I recently switched my image pre-loading to more "efficient" code I came across.
However, it doesn't seem to be working as the images only load on mouse over.code...
Any way to have a "status bar" popup while images are loading???
View 3 Replies View RelatedBasically what I'm trying to achieve is when a new image is selected(clicked), the 'click' passes the new image name (and width, height) to the 'changeimg' function, I want this function to fade the current img so we can see the back ground wait img. then when the new image has preloaded successully, replace the current image and fade it back to full. It appears to do this mostly, but its not preloading the image, sometimes the contain will exapand to the new size and I'll see the image loading into it.
I'm wondering if I'm using the preload (new Image()) correctly, I cant locate any examples similar to what I'm doing. Most exapmles I see all appear to be to do with image rollovers. Which isn't what I need, I also do not want to pre load any images until they have been requested.

I have almost 300 photos that I want to have in a gallery that is easy to use. I would like to avoid making 300 list items (as is necessary with all of the auto rotators and other jquery plug ins that I've found) but to have the images load straight from the folder after the rest of the website has loaded.
It wold be nice if maybe there was a pretty horizontal scroll bar or something and the image in the middle of the page was biggest if possible, but I'm really not picky. I don't know what the best way is to display so many photos! They don't need captions or anything.
I'm trying to preload an image before it fades in and I'm using the following code to do so. Could someone please tell why it doesn't work? The layer fades in and then the image suddenly shows up.
View 2 Replies View RelatedI have a large image that I change by clicking on some small images to change it.
I use this code to preload images and then fade in, but it doesn't look nice. Once the images are cached into the computer the fading is perfect, but the first time it seems like it fades at the same time as it loads. I wonder if it could be done in some other way? Perhaps use a callback or preload all images into an array, but I'm new and don't really knows how to put i together yet?
$("#bild1").click(function(){
$("#main_image").attr("src","bild1.jpg").hide().fadeIn(1000); });
I use the code above for each thumnail images.
This code seems so simple but I can not get it to work. I am trying to preload images for use in an image swap. This is the code I am using:
<body onLoad="preloadimages('ro_bui.jpg', 'ro_mar.jpg', 'ro_sto.jpg', 'ro_mec.jpg', 'ro_pai.jpg', 'ro_fib.jpg')">
<script language="JavaScript" type="text/javascript">
<!--
function preloadimages() {
var roimages=new Array();
var arguments=preloadimages.arguments;
for (i=0;i<arguments.length;i++){
roimages[i]=new Image();
roimages[i].src=preloadimages.arguments[i];
}
}
-->
</script>
In the mouseover event I have
<a href="marina.htm" onmouseover="document.images['ro'].src=roimage[0].src" onmouseout="document.images['ro'].src='ro_base.jpg'">
for each rollover....
I've got 2 questions if that's OK. I have a number of scripts running on a site i'm working on and I think I may be getting a clash with the image preload and another font resizing script. As I am new to javascript I have picked up the code from elsewehere. I am trying to get my head around it reading tutorials etc but am getting stuck when it comes to multiple scripts on the page
There are a number of scripts running: browser detect, png opacity, image preload, layer show/hide and a font resize.
here is the site
Q1 In IE5.5+ on the PC neither the font sizer nor the image preload is working - i think it is a clash of onload events. Can anyone suggest a fix?
Q2 I think there must be a better way to have my images preload. The current code is the dreamweaver version. Is there a better way?

I'd like to know if there's a possibility to select a random image .. but .. from a directory.
I've seen many posts regarding this subject, but all of them show the procedure once you have the image names inside an array.
I need to know how to select a random image from a directory that's filled with them, like let's say /public/images
capturing just the file name rather than the entire path of the SRC on my input type="image". Basically when I hover over an image, the Default Image should change to the image being hovered on. Here is my code, can't quite get it to work. Sorry I'm very new to JavaScript
<html>
<head>
<script language = "Javascript">
function ChangeDefault(src)
{
//document.frmMain.DefaultImage.src = src <--Doesn't work at all
alert(src) //<---Displays the entire file path, want just file name

I'm trying to find a JQuery plugin that will:
a) preload all img's and background's on a given page
b) display an animated gif in the center of the original's img's or background's container
c) fade out showing each image once it's downloaded
d) as a consequence of (a) allow the page to render (show) quicker even if (depending on server speed, connection speed and user computer speed) the remaining images are still in a 'load state'.
e) is based on JQuery so not to increase page's footprint via adding Mootools, Prototype, YUI or the like (unless the additional 100KB or so is so worth it).
I've scouted Google and there a few out there but amazingly none seem to focus on doing this for a web page's image's but rather seem to focus on galleries/lightbox windows and so forth.
I am working on a script which will get images (.jpg & .png) from a directory in my server.
HTML Code:
jQuery.getJSON(url, function(data) {
var images = jQuery.map(data.photos.photo, function (item){
return '/images/';
});
callback(images);
});
}
At, /image/ , I want to get all of the images in a from a set up directory full of images, named as 1.png, 2.png, 3.png ,etc. Lets say that the directory of the images are in /images/, How do I set it up so that this script gets the images?
I have had some experience with JavaScript. I have therefore developed a very simple slideshow. The source code for this can be seen below:
Code:
I feel this works as it should as I can move from image to image and also have it to run automatically. However, I now want the user to be able to browse an image and the image to be saved to the default directory where the other images are stored.
I currently have a script after searching online which browse's and opens the file, although this is in a new window, whereas with the slideshow the image is to be opened within the table. The browse code is shown below also:
Code:
The save function i have found only through research works in IE via the execommand. Any ideas how i could get this to work on other browsers or anthoer method of saving the image into the array?
I'm working on a project for work and I'm having some issue trying to distribute to program the smoothes as possible, on idea I had was using Javascript, Im kind of new at this so ill explain to you what Im hoping to do. Basically Im looking for a onload= function when the .hta opens it would get a file from lets say G:\path\path1\path2\file.hta to C:\path\path1\folder So it would take the file and copy past it in another folder from a different directory. If a popup message could popup saying completed
View 6 Replies View RelatedI have a banner that has image navigation on the lower right. The navigation links are images which, when clicked, change the banner without reloading the page. The actual switching of the banner is working when each image is clicked.
However, my problem is this:
The page itself is long and must be vertically-scrolled to see the entire content. Because of the scrolling, the banner could appear anywhere vertically on the page. And whenever I click the banner navigation hrefs, the page "jumps" so that the banner is at the top. The page should really stay in the fixed position.
I'm not sure how to set it up so that no matter where the banner section is on the scrolled page, that the page stays in the same position when the navigation is clicked.
My href's in that navigation are set up as :
Do I need something in my script so that the page won't jump? Or am I missing something in the HTML?
I shoud give a "value" to an DIV's ID that change following the name of the
directory where the file is.
For example the file is here:
www.website.com/web/01/file.html
Is it possible with javascript to give the value "01" to the DIV's ID?
<div id="namedirectory"something inside </div>
so it could be readed as:
<div id="01"something inside </div>
I found in internet this one:
<script language="JavaScript">
fullpath=location.pathname;
document.write(fullpath);
document.write('<br />');
result=fullpath.split("");
document.write(result[5]);
</script>
it's something that could work?
I don't know how to recall the value in the ID...
Who can tell me about some function which just preload some little poor images 4 me?
