problem is i dont think java would be capable of editing the background image - maybe I should check....
Your code does the same thing mine did:

It only displays the file named 1.jpg...

this file has the same script i posted above, it does print a random number between 1 and 4.. besides javascript IS capable of doing this, search the forums :)

i know the code for the image, and the php script does work for a normal image, it's just that it wont work with the background, i have no clue why.
Ill try to post this on a specialised php phorum....

you have to enable the random function for php... hold on let me find it...

you have to use srand() to initialize the random-ness in php.

my server allows php4 and all that. i dont think it is way behind... What I might do is try to generate a random CSS background in php and see if it works...

What I need now is some sleep.
