super smilies - background a problem

[DocBenny]

First I would like to ask if someone knows where I can get some good 3D smilies that I can include in my forum. Smiley Central has some nice ones, but they're too big I think, and even if I wanted to upload them, they have a boxed background of white which doesn't blend well with my forum background, and I don't know how to take that out.

I'll upload an attachment of an example.

Is there a way to fix this, or better yet are there any smilies like these out there that are a bit smaller and can blend with any background?

Thanks
