So i have been looking for a head recently and i found a few that look pretty cool, but have a gif. I uploaded each of them all with and without transparency and yet they still get denied for transparency. If anyone can help me with this, it would be greatly appreciated. Thanks.  

Was it denied for transparency problems: solid black or white, or transparency problems: visible background?  

It was denied for true black and white i think. whenever the head blinks, a box appears around the head.

Well actually it kept getting denied for the transparency button not being on even when it WAS on so idk what that would be qualified as  

Hmm, I guess Era uses slightly different denial reasons than Classic. Anyways, if a big box shows up around it in part of the gif, you will need to remove it from those frames yourself. The set transparency box only works for images that are not animated (png).
