No matter what, if it currently has a white background, you are going to have to "erase" it without damaging the actual image. PSP has a background eraser tool that can help with this. Photoshop I'm sure has a similar tool, but I don't use Adobe bloatware and rapeware. And your file format choices are GIF and PNG. GIFs are limited to 256 colors, and the transparency is all or nothing. This means if you have semi-transparent pixels, you are going to want to blend them with whatever your background is to prevent that stair-stepping effect. PNGs do have support for alpha-transparency, which allows for semi-transparent pixels, so this might be a better choice depending on what you want.
