I am having trouble getting the rounded corner banners and buttons to show on a dark background. They are appearing with white corners and look very unprofessional. Like, if you go to www.logomasterpiece.com/ and scroll down the right sidebar, the CafePress Mother's Day banner (as well as the Photoshop button) do not have transparent corner. Does CP not save their buttons with transparent backgrounds or do they expect that all their buttons are going to be placed on a white background? It just looks crappy.

I have a possible fix for you......Upload the banner to your graphics program,fill the white corners with a color that is not present elsewhere in the image (green would work for both) then replace or swap the green for alpha or transparent.

You might need to scale the pink one up a bit if you have troble hitting the white bits on the corner----once you zap out the white resize

hope this helps, if not they would look better with regular sharp corners than rounded ones that didn't quite work.

I'd check it out, but you're running a script which disables contextual menus. Usually when I run into something like that... I run from the website in question.

Transparency is a problem for older puters, and GIF quality isn't always up to par... So the old standards for banners remain popular.
