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!)
View 4 RepliesI trying to:
- preload an image
- then call it as a a background image.
But cant get it to work- here is my 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 ?
Will this code suffise to preload two given images into the browsers' cache, before the page has loaded?
// 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'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?

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?

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.
provide javascript to create something like the image below: Things I can't workout are:
1. top and bottom background colors as the above image
2. add two text
3. border color same as top background color

I am building a simple t-shirt creator app for my shop and I am using the interface.js library: [URL].. docs/drag to drag/drop and re-size the graphic on the shirt background image.
Once the user has chosen a spot to put the graphic, how do I save the background image of the t-shirt with the image they dropped in the correct spot? Like, to merge the two graphics in place?
I am trying to recreate this functionality on my website where you can drag a background image around and when you get ot the edges of the image it bounces back to the edge of that corrosponding side. have a look at the site in question - [url]

So when it does it, it is getting the URL of the generator (I logged it. what is actually being passed is [URL] This would require a server call to generate a new image, In this particular application, even if it wasn't exactly the image y had it would be acceptable.

I have a LARGE, hi-resolution image that I am trying to use as the background for a page. Because it is so large, it takes a while to download. Because of this, I wanted to load the image behind-the-scenes and show it once it is downloaded.
To accomplish this, I'm using the following JQuery code:
This code clearly downloads an image and appends it to my DIV element. However, I really want to set this downloaded image to the background-image CSS property of my DIV. The reason why is because I have content inside the DIV that should serve as the foreground.
How do I dynamically download an image, fade it in, and use it as a background?

View 7 Replies View Relatedall i want to do is make the background image of a couple of pages fit perfectly in the browser window of different screen resolutions.
the problem i am having is that i am using 1024 x 768 screen resolution. and the background images fit perfectly in the pages for me but when someone with a lower or higher resolution views the page, the background image either gets cutoff or starts repeating.
is there any code that will fix my problem??
i have found some code (see below) that resizes the image according to the window size but it is for an image on the page and not the background image. Code:
With image elements I can do <IMG src="..." onLoad="..."> where
the onLoad is supposed to fire upon the image loading. Is there an
event that I can trap for once the background image in
<BODY background="...url..."> is loaded?
I plan to render a series of maps which sometimes take a while to
compute (on the server) so I'd like to know when subsequent ones
come in.
Failing that, can I assign an already loaded image to the background?
