You must replace img src=yourpic with img src=image.php etc. Anyway there is a problem with the cache, if you are not using the cache rules (Apache) you're ok. Using this script you get "200 ok" instead of "304 not modifyed", so the thumbs are reloaded all the time. Tested on hostgator, using Pagespeed and Live HTTP headers (firefox plugin). So, I've removed the script from my CMS :-( Awaiting the response/suggestion of Joe. Regards. Read the comment of zach.

Do not use Etags, it's slow down the website performances. I tried some experiment with your script into a real remote server. It seems that there is a mistake with your header() functions, because invalidate all the directive with apache (about caching). Plz, remove etags, first of all. Take a look here: http://developer.yahoo.com/performance/rules.html Anyway your script is good. Back to more update (I hope!) Regards. Oh another things…

Great script, thanks for sharing. I've integrated my script in my CMS, but... there is a serious problem... The leverage browsing cache is not work using this script. So, the images is served correctly, and not scaled in HTML... this is very good, but the browser cache is not working. This is more evident using Internet Explorer 8. If you refresh the page, you see that the images are loaded/downloaded again! The rule: Header set Cache-Control "max-age=29030400, public" is not working, all the images are dowloaded ex-novo all the times! I have used a rewriterule to have clean urls, the cached images as the originals. However the images are loaded all the times and are not cached by the browser. This makes the script useless for performaces purpose and to remedy to the problem of HTML scaling... but with the HTML scaling all the images are cached by the browser. Can you fix this? Regards.

I believe that the process would involve splitting the GIF up into its frames, resizing each frame, and the re-splicing it back together. @Daniel: That is actually how it is designed to work. You should be able to use a relative image request (<code>image.php?image=/img/something.jpg</code>). @Trevor: You can do this. Just set the crop-ratio to 3:2. @Rizwan: Yes, you are correct. For URL parameters that contain reserved characters like plus signs to work, you will need to escape them somehow. As you mentioned, PHP has a function for this called <code>rawurlencode()</code>. @WTF: I have been working on <a href="http://code.google.com/p/smart-lencioni-image-resizer/" rel="nofollow">an OOP version</a> that you might want to check out. If you do, be sure to grab the latest from the SVN (currently at r77) instead of the 2.0b2 download. Although, most of the methods are restricted so I am not sure how "reusable" it will be out of the box. With a little tweakage I don't think it should be too bad.
