Thanks for pointing out your page, it was very helpful to how it's done.
BUT I still get *black* GIFs and JPG's, only EPS works. One way to get
at least a non black curve is:


anim1 = Plot[Exp[-(x - 1/3)^2], {x, 0, 10}, PlotRange -> {0, 1}, 
    PlotStyle -> {Blue}, Background -> GrayLevel[1]]
Export["anim1.gif", anim1, "GIF"]

This produces a blue curve on black background. This is of course not
satisfactory and fails with PLOT3D. 

I am wondering if this is a Linux specific problem, since you work with
Windows. Is this a known problem or specific to my installation?
