Dave, thanks for all your input and insights.  Perhaps I should have 
said this before, but this is what I'm trying to accomplish.  I plotted 
a several graphs in gnuplot that show the evolution of a wave pulse as 
time progresses (one plot for each increment in time).  I can save each 
plot as a .png and I can use QuickTime Pro to create a nice movie of 
the wave pulse's evolution; however, I would like to create an animated 
logo for a Web page and thought that an animated .gif would be the way 
to go.  What would you suggest?  Small bandwidth and not requiring a 
reader to have any special plug-in would be plusses.  (I don't have 
Photoshop, but I do have the Gimp.)  Thanks again.
