Just spent a year in Iraq, so I'll try to add my two cents worth.
What's the point of this? Who is going to get the cameras? Is someone going to pass them out to Iraqis, ask them to take photos (possibly at great personal risk) and then return them to the giver so he/she can somehow mail them back out of the country? It is possible for people to get film processed there, but most people are going with digital because it's just easier and less hassle with "infrastructure" (labs, chemicals, film supply, etc.).
The Iraqi people have plenty of digital cameras (and film cameras) and there's no problem getting all the "snaps" they want, but if you're looking for political/security images of some kind, it's not worth the risk.
Frankly, I just can't see this idea going anywhere useful. There are lots of images out there already of Iraqi daily life, weddings, people in cafes, kids at school, etc., along with all the usual news photos, so what's missing?
FWIW. . . .
