As such the caching requirements for an image are unique and absolutely not connected to the caching restrictions of the page it is referenced from. That said: if your page is non-cacheable, images it contains will still be cached if the server allows this. If you're image tags look like this: <img src="../images/somepic.gif"> it's most likely the image will be cached (like any other "static" file). For a tag like <img src="../imgdb/getimg.php?id=4711"> the script "getimg.php" would need to issue the appropriate cache directives to allow caching. -- >O Ernest E.
