The 1st photo was uncovered by Little Green Footballs
It was quickly picked up here on FR
Reuters admitted the first photo was doctored and fired Hajj
The second photo (F16) was discussed at Jawa, http://www.freerepublic.com/focus/f-news/1678950/posts
now they are admitting that photo is doctored as well
Look at post #3 for a history of the doctored Beirut photo.
This guys has a good candidate for photo #3. Not so much a doctored photo as a staged photo.
