I have a couple of pictures I'd like to posterize, eg reduce to maybe between 4-16 colors only. Can this be done with iPhoto and if so how, or if not, what else could I use that's free ? (for an experiment with 2 photos buying something seems over the top) . I took a look at the iPhoto help but couldn't find anything.
 
No, iPhoto doesn't do this. I'd use the GIMP.

If you're on Leopard, you'll also need to install X11 before the GIMP. You can get it here.
