True actually! Thanks Wildhoney. :)
It'll be a little harder when someone requests to upload a new twitter.com favicon, I should somehow check if there's already a: twitter.com.ico file in that dir. Instead of keep leeching Twitters bandwith each time someone wanna upload this ICO. I'm super new to working like this in PHP, so some help with how to do that would be awesome!

Thanks. :)
