Never trust a file extension to be what it says it is. I could easily rename an executable to dot jpg and trick your script into believing it was an image - getimagesize will attempt to return the correct mime-type for the file that has been uploaded if your expecting only images. The other option would be <a href="http://us3.php.net/manual/en/ref.fileinfo.php">FileInfo</a> but I don't see any reason you wouldn't be just fine using getimagesize.

I'm not seeing the JavaScript that VI is mentioning but maybe I missed something there; outside of that, zomg, I haven't seen the CENTER element since Netscape.
