what i dont understand is:

image+tmp

form what i see it would be something like:

image.jpg?8:31:12

this can't be an image src, or if it can what it does??

its a random number so caching dont cause a problem.

Here, i made this a while ago. It probably has some stuff you don't need in there, but it gets the job done. :D

Tell me if you have any questions.

Code:

<html> <head> <title>Ad Cycle</title> <script language="javascript">  </script> </head> <body onLoad="update()"> <div id="obj1" style="position:absolute">Loading Image Cycle...</div> </body> </html>

would it be because you have the same name for the image.

Like i said, i wrote it a long time ago for one of my friends. The part that isin't working in yours, works in mine, so i thought that you might be able to use it.

because the image is updated on the server... It is being used for a web cam, and i dont want to repeatively update the whole page...

the page the code is on is at http://frankhdale.demon.co.uk/cam/default.asp
this is the exact code that came from the visionGS software im using for my webcam.

sebs: thanks, i will try that when im back at work monday, thou i might do it in the week if i can be bothered :D:D
