AndreaMosaic is a free but powerful photo mosaic application. Photo mosaics are images made up of lots of other small images. When you look closely at a photo mosaic, you can see the small photos that have been used to produce it and these are more obvious when less mosaic tiles have been used.
In this step-by-step tutorial, I'll show you how to produce your own photo mosaic using your own images. Before you get started, you'll need to download AndreaMosaic and install it on your computer, if you haven't already. It's available for Windows, OS X and Linux.
