I would like to use one of the Dungeon Warfare achievement pictures as an Steam avatar.

Sadly, achievement icons come in a fixed size of 64x64 pixels.
So the result looks kinda blurry.

Steam supports avatars up to 184x184 pixels.
As a publisher you can configure a list of avatars an game owner can choose from.

It would be awesome if you could upload most of the achivement pictures in a higher resolution there.

I think nearly all of them are looking cool as an steam avatar:

Especially because they have this lovely little frame around them :)
