Mash Up Your Photos
ImageMagick is the ultimate tool for making collages.
This is the first in a series of hacks about creating mosaic images. In this hack, we’ll build an image that contains a number of other photographs, randomly positioned and rotated. In the course of doing this, we’ll learn a bit about the incredibly useful ImageMagick library (plus, we’ll make a pretty interesting-looking collage).
What You Need

This hack relies on the getPhotoList.pl script [Hack #33] and the getSnaps.pl script [Hack #34] .
