Will the size of animated wallpapers be larger if the original pictures are JPG's?

The original pictures for my animated wallpaper are JPG's. Then I use JASC animation shop to convert them to GIF's.
Would it better to have the original pictures as GIF's from the beginning, so JASC wouldn't need to convert them? Would the resulting GIF animation be smaller then?

i don't think it matters, as either way you have to convert it to gif at one point or another. if you start out with gif, it's probably been converted earlier, or been low-quality (gif) from the beginning. if you start out with jpeg, you conevert later in the process and you get lower quality pictures (gif) which you compile into an animation.

OK, there is no use in using original gifs instead then I guess. The problem that I have is that my customer MediaPlazza requires that most of the animated wallpapers should be less than 15 kb. It seems impossible to make them that small and still look good. I am using JASC animation shop and even if I only use 5 frames and optimize it as much as I can with the optimization wizard, the wallpapers become too large.(about 20 kb)

Here are examples of my original pictures:

How can I make the wallpapers smaller?

compress them higher when you convert them to gif and don't make the resolution higher then absolutly nescessary.
