Not yet. Ctdonath2: I don't know at what magnification you were seeing the bomb - which is a Texas Instrument GBU-12 (Paveway II) - when you made your comments. Here is an 8x close-up (800%) of the smart bomb and that blocking behind the tail is definitely not consistent with any other part of the image.
I ran the image through JPegSnoop, which identified it as a Sony Cybershot photo imported into Photoshop, saved at Save as 7, and then resaved at 75% quality by one of many image editors having the same compression signature. The fact that chroma subsampling is 2x2 limits the field to only a few, like Photobrush or Irfanview.
The Error Level Analysis also confirms that the rectangular blocking artifacts are off by themselves and do not follow the contours of the bomb.
Compare it to this photo of a Copperhead moments before hitting a tank.
And the ELA of it:
This photo was shot by an Olympus camera, imported into GIMP, and then saved at 87% quality. (There are four Olympus models listed; but, it's probably the C2000Z because of its massive zoom lens. The subsample does not match, however, I'm still betting on the C2000Z being the one). When you look at just the bomb enlarged 6x (600% to make it about the same size as the GBU-12), you can see consistent blocking on it and all throughout the the picture (although the focus is soft and not as sharp as the Iraq bomb, and because the Copperhead photo is legit):
IMPO, the bomb was Photochopped onto an existing photo - a practice so common in the Middle East that the vast majority of photos coming out of Iraq, Gaza, and Lebanon have been chopped for maximum propaganda effect.
