These functions can be used to read and write animated gifs. They are intended for use with 4-D image arrays of various type. Supported types include RGB/RGBA arrays, as well as indexed images. Indexed mages with transparent content can be specified by a corresponding vector of indices, or by simply appending an alpha channel to the image array itself. When writing, colormaps, transparency, and disposal method can be specified per-frame or globally.
Optional functionality requires the use of imagemagick and is exclusively intended to work in a *nix environment, but default settings should work on other systems. I have no intention of modifying this to be more robust in that aspect.

Write image stack to an animated gif
These tools are merely a subset of the Matlab Image Manipulation Toolbox (FEX)

Jack: That sounds reasonable. I've added that to the todo list.

Great gifwrite(). How about having a frame range for gifread() so one can efficiently test methods used on large GIFs, for example?
