So my avatar was already transparent, but it was 64x75 pixels and this new forum layout caused it to stretch and screw up its aspect ratio.

So I decided to upload my avatar at proper 75x75 pixels this time. But now my avatar became completely blacked. As if the transparency is not working. I made my image was transparent [Check several times through photoshop]. So I guess somethings messed up here. Because transparency was working before I uploaded this new picture.
