hello,

i use a simple code below to choose a random image for my site header:

<script language="javascript" type="text/javascript">

p=65*Math.random();
d=parseInt(p);
document.write ("<img src ='L:/webroot/pics/"+d+".jpg'>");

</script>

there are 65 images in the folder, starting from 0.

all is working pretty wel, but - sometimes it gives a blank result, not the image.

can You please help?
thx

Perhaps try using the IsNaN function to do some error checking to make absolutely sure your getting a correct integer and not just NaN.

edit:
Just another little flaw in your logic I just noticed is that by multiplying by 65 your never going to show picture number 65 since even 65*0.99 will only result in 64.35. Thus since parseInt only removes everything after the decimal (including the decimal) your highest possible result will be 64. So, try multiplying by 66 instead.

That's not a flaw. If he starts at 0, the last file number will be 64, not 65.

I'm thinking that the reason your code is acting up is because it's accessing a file that does not exist. You should make sure that you have all images from 0 to 64 in your folder.

If not, use alert (d) to see that you're getting the correct numbers.

Good catch.
