Newbies, don’t upload exploits with your images!
Posted by Sarah King in Technical Discussions
Manuel Lemos from phpClasses.org has written an excellent post about about the risks when allowing users to upload images. It’s not something I’ve done alot but lets say you have a generated image such as this one - with a .php extension. I could upload it to your server and have it served from there - not much use to me because it would fail to update.
The next guy, however, might be uploading a malicious script that might take over your server, send spam etc.
