Yeah, you really should convert all those high quality .jpg(s) to GIFs. You probably used such a high quality setting to eliminate artifacts, but if you use a GIF with a good compressor, the change is quality will hardly be noticable, there will be no artifacts, and the file size will be cut by over 80%. A pointer: use even less colors for smaller images. You can probably get away with 16-32 colors for the buttons, and might want to keep the banner at 64-128 colors.
