Jpg/Jpeg files don't support any transparency so it will always add a white background. PNG is recommended as it maintains a lot of the original quality where as GIF supports only up to 256 colours (really, this is low), but .GIF is your only option if you want to create an animation with transparency. Unless you're good with Flash, a .SWF will do great, low file size and high quality, though making it clickable requires a bit of coding knowledge in Flash. That should help!
