Can you join GIFs and/or Animated GIFs into a single Animated GIF?

Does anyone know if it's possible to join several gifs or animated gifs into one animated gif (ie. concat the frames together into one master animated g开发者_StackOverflow社区if)?

I'd like to have some server side function to do this.

The file will be identical in dimensions, mode etc, just their content will differ.

Thanks!

Try using ImageMagick to create the animated gifs (some examples here).
