All the headers and all the META tags in the world won't get EVERY browser and EVERY caching / proxy server (AOHell) to stop caching. If you really truly absolutely MUST have no caching at all, generate random/unique URLs for your content. <img src="/images/phpscript/nocache=<?php echo mt_rand()?>/whatever.jpg" /> phpscript can be ForceType'd to readfile whatever.jpg (or to fopen/fread/echo if your JPGs are large) and the nocache will guarantee the browser won't cache it. More precisely, the browser WILL cache it, but you send the browser a new URL every time, so it renders the cached item useless. Maybe if the browser-makers actually honored the no-cache headers they keep making up out of thin air, I would feel bad about wasting their cache like this. But they don't, so I don't. You need the .jpg at the end for IE to do the right thing. -- Some people have a "gift" link here. Know what I want?
