Quick and dirty way to help avoid image caching in the browser: use rand() to append a random number to the end of the img src element: echo <img src=\"blah.gif?\".rand(1,999)."width=\"100\" height=\"100\"> browsers will see <img src="blah.gif?453" width="100" height="100"> They ignore the stuff past the ?, but it's enough to make the request different from the previous one, meaning the browser will get the image off the server again. Not 100% reliable, but what is? -- http://www.php.net/manual/en/function.rand.php http://master.php.net/manage/user-notes.php?action=edit+22093 http://master.php.net/manage/user-notes.php?action=delete+22093 http://master.php.net/manage/user-notes.php?action=reject+22093
