Although my knowledge of the GIF format is limited, I believe one thing you should also keep in mind is that they must only contain 8-bit color information (translational to only 256 colors), as opposed to RGB that has 32-bits (translational to thousands of colors - perhaps more but I am limited by my monitor). So you're much better of (as already advised by Rina Gribovsky) using an RGB file with JPEG compression. However, before you switch formats, I would strongly advise doing some tests concerning the level of compression you will be doing using the JPEG format, and whether or not the results are satisfactory. Since even though you can obtain substantial drive space savings using JPEG, the amount save is inversely proportional to the amount of retained image quality.
Best of luck,
