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.

Your avatar still looks cool tho

Woops! Thanks, I'll fix this later today.

As Jelly Jam said, the effect is kind of cool in your case though.

(this was fixed, but unfortunately you'll need to upload your avatar again)

Thanks, its working now.
