Well I figured I would jump on the bandwagon here, so I held a certain Hippo at gunpoint and forced him to photoshop a Santa hat onto my avatar. He botched it up, but since it's Christmas I only killed his cat. The compression artifacts look terrible too. Is space on the gamedev server really so precious that we can't have PNG avatars?
Edit: What the hell? the extension is .png but the content type is image/gif
