How to get better transparency with GIFs?

Question

Is there any software, plugin or technique that would allow creating/exporting PNG-like GIFs with smooth transparent edges, at least for smaller images like bullets or butto

Answer 1

As far as I recall (I've not used GIFs for quite some time), a GIF doesn't have a variable transparency - a pixel is either transparent or not. You could simulate transparency by blending with the background image, but that would rely on having a static, defined background.
