As I undertsand you wrote a script that generates an image, and give it back to the browser in an <img src=...> html tag. Am I right? I hope I am, so I continue :)) Images can be cached in many places (proxies, browser), but definietly not in php. Your script that generates in the image and should be called every time by the <img> html tag, won't ever called again if the previous image were stored somewhere. You should send "pragma no-cache" and other http headers (many posts were on this "cache headers" topic) from the script that generates and gives back the image. Or another sollution is that you can call your script with a random number or better with the current date and time, so you images's name won't be the same, and caches can't give back the old image. for example: <?php echo"<img src=\"generatebackground.php?x=".date("YmdHis"). "\">";?> Arpi
