Slideshow screensaver with moving gifs

I have a large collection of humorous pictures, mostly jpegs but a few very nice moving gifs. I have my screensaver set to Slideshow to display them all. However, WinXP Slideshow only shows the first frame of a moving gif.

Does anyone know of a Slideshow Screensaver that will show an entire moving gif, as well as the jpegs?

Thanks.
