IE doesn't support transparent PNG it seems.
I don't have access to IE btw, and don't care how it looks on it.
About the color, someone suggested to add some so I tried it.
Huh thats weird... you image looks different in IE (used firefox when posting the previous) In firefox I see a transparant background with yellow between the feathers and in IE I see a yellow box where the symbol is placed in :S
