Forum:Transparency

Hi, I'm new here so I don't really know what's going on (check my userpage), but I was wondering if we had any rules about adding transparency to images. Just just skimming through the wiki, I can see tons of images that could benefit from it. However, I thought that if no images had trans, there might be a reason for it. — Matthew2602 (talk) 11:35, June 22, 2011 (UTC)
