I have a filenames like sint-001.jpg , sint-002.jpg,... running in a loop
a)is there a fast way to get those zeros before the number or a way to perform an function like int() in VB or perl and then get each digit by dividing-rouding-multiplying?
b)is there a way to dedect what the last one is?

I made this slide show script and it works pretty good. With it, you don't have to know how many images you have. I preload the image to see if it exists. If it does, it shows it and continues to the next image after four seconds. If it doesn't, it starts over. I put a line in there to adjust the zeros too.

<html>
<head>
<script>
var doLoop=true;
var counter=1,img='',tester=new Image();
tester.onload=isGood;
tester.onerror=isBad;
function testImage(c) {
c=c.toString();
c = (c.length==1 ? '00'+c : (c.length==2 ? '0'+c : c)) ;
tester.src='/data/images/sint/sint-'+c+'.jpg';
}
function isGood(){
document.getElementById('imgView').innerHTML='<img src=&quot;'+tester.src+'&quot;>';
counter++;
setTimeout('testImage('+counter+')',4000);
}
function isBad() {
if(doLoop){
counter=1;
setTimeout('testImage('+counter+')',4000);
}
}
</script>
</head>
<body onload=&quot;testImage(counter)&quot;>
<div id=&quot;imgView&quot;></div>
</body>
</html> Adam
