Color matching magic?

I'm trying to figure out if there's a tool that can do this (programmatically) or if someone has some script idea/suggestion for what I'd like to do. I have several 130px X 130px images (one per day) that I collect. I'd like to have a script run that will read in the folder(d) where these images are stored and with ImageMagick, create a montage of them. I need to be able to set how many images wide by how many tall I'd like it to be, and I'd also like the script to organize the images in a rainbow pattern based on their color. Very much like what a PhotoMosaic program would do with images, create a color index of each one, then build a larger image with these little ones. Anyone have a suggestion of how to, or where to start with this? Thanks. -- H | I haven't lost my mind; it's backed up on tape somewhere. +-------------------------------------------------------------------- Ashley M.
