background image

I have this little code wich is working quite good, it makes a slide
show on the body background, anyone could guide me on how to add a
fade effect as a transition between the images??

var Pic = new Array('cow2.jpg ','cow3.jpg','c ow4.jpg');
j=0;
p=Pic.length;

function preLoad() {
var preLoad = new Array()
for (i = 0; i < p; i++){
preLoad[i] = new Image();
preLoad[i].src = Pic[i];
}
}
function runBGSlideShow( ){
document.body.b ackground = Pic[j];
j++;
if (j (p-1)){
j=0
}
setTimeout('run BGSlideShow()', 2000);
}

</script>
</head>
<body onload="runBGSl ideShow();preLo ad()">

You can use the JQuery. There are already some method to make
animation in JQuery.

It is normally done using setTimeout or setInterval to step through
various levels of opacity with a pause of say 50ms between steps -
increasing one image while decreasing the other. Search the archives
for "fade opacity".

You might like to look at this post in another group by Peter
Michaux :

There was also a thread there on opacity performance - it's a little
old now but likely much of it still applies. It also suggests
strategies for ensuring the fade works well in different browsers and
slower platforms.

Hi there, I need to use a background image in a TR that does NOT restart everytime it hits a TD. Can it be done? Specifically, if you set a background image for an entier table, now mater how many TRs and TDs you have, it will show the complete/unfragmented image (as long as you don't over-ride it). When I set a TR background image, every time I hit a TD it "re-seeds" the image. I want to have a TR that shows an 800px image in it's
