in reply to Creating an animated gif with GD

there are several modules for working with images -- GD, Imager, PerlMagick, probably many more. Is there some comprehensive-ish comparison of the offerings out there?

I usually use gifsicle for animated gifs. It works well. Then you can use any of GD, Imager or ImageMagick to make your frames, and feed them to gifsicle like 

system("gifsicle -lforever $my_stuffl*.gif > $my_stuff.anim.gif") ;

for GD, try Text to animated pseudo-braille GIF and see Image::Magick GIF Animation Speed for ImageMagick usage.
