Pop Up Window Images Load Too Slowly - 3/2/2002 0:28:08
Hi Gang!
I have a pop up window with 14 images in a slideshww that take too long to load.
Here is the link to the page that opens the pop up window.
www.maranelloautosales.com/test1.htm
Here is the code of the slideshow
<script language="JavaScript">
var Slides = new Array('http://www.maranelloautosales.com/images/2413/13b.jpg',
'http://www.maranelloautosales.com/images/2413/1b.jpg',
'http://www.maranelloautosales.com/images/2413/2b.jpg',
'http://www.maranelloautosales.com/images/2413/3b.jpg',
'http://www.maranelloautosales.com/images/2413/4b.jpg',
'http://www.maranelloautosales.com/images/2413/5b.jpg',
'http://www.maranelloautosales.com/images/2413/6b.jpg',
'http://www.maranelloautosales.com/images/2413/7b.jpg',
'http://www.maranelloautosales.com/images/2413/8b.jpg',
'http://www.maranelloautosales.com/images/2413/9b.jpg',
'http://www.maranelloautosales.com/images/2413/10b.jpg',
'http://www.maranelloautosales.com/images/2413/11b.jpg',
'http://www.maranelloautosales.com/images/2413/12b.jpg',
'http://www.maranelloautosales.com/images/2413/14b.jpg');
// DO NOT EDIT BELOW THIS LINE!
function CacheImage(ImageSource) { // TURNS THE STRING INTO AN IMAGE OBJECT
var ImageObject = new Image();
ImageObject.src = ImageSource;
return ImageObject;
}
function ShowSlide(Direction) {
if (SlideReady) {
NextSlide = CurrentSlide + Direction;
// THIS WILL DISABLE THE BUTTONS (IE-ONLY)
document.SlideShow.Previous.disabled = (NextSlide == 0);
document.SlideShow.Next.disabled = (NextSlide ==
(Slides.length-1));
if ((NextSlide >= 0) && (NextSlide < Slides.length)) {
document.images['Screen'].src = Slides[NextSlide].src;
CurrentSlide = NextSlide++;
Message = 'Picture ' + (CurrentSlide+1) + ' of ' +
Slides.length;
self.defaultStatus = Message;
if (Direction == 1) CacheNextSlide();
}
return true;
}
}
function Download() {
if (Slides[NextSlide].complete) {
SlideReady = true;
self.defaultStatus = Message;
}
else setTimeout("Download()", 100); // CHECKS DOWNLOAD STATUS EVERY 100 MS
return true;
}
function CacheNextSlide() {
if ((NextSlide < Slides.length) && (typeof Slides[NextSlide] ==
'string'))
{ // ONLY CACHES THE IMAGES ONCE
SlideReady = false;
self.defaultStatus = 'Downloading next picture...';
Slides[NextSlide] = CacheImage(Slides[NextSlide]);
Download();
}
return true;
}
function StartSlideShow() {
CurrentSlide = -1;
Slides[0] = CacheImage(Slides[0]);
SlideReady = true;
ShowSlide(1);
}
</script>
Any Advice as to why the images load so slowly and when they do they load in segments.
Thanks in advance
Carlo

Hi Carlo
Easy problem to fix.
Just reduce the size & quality of images to speed up the process.
I clocked one image at 170kb?? way too big for what you are trying to achieve.
Ideally you need to get them down to 15-30 kb.
Cheers from the Outback
