There are 2 logos displayed because of how they display in IE vs Firefox and Opera. PNG is the larger image (filesize) of the two, the GIF file is the one that would actually be displayed on any website that I put these on (most likely acedanger.com). On a side note: IE sucks. You should feel ashamed using it, unless you don't care, then nevermind.
