The Jane's report says the photo is from a video aired by Al Jazeera, which I have not found. In the region, Turkey does still operate F-4s (and lost one to Syrian fire as recently as 2012), but is not likely to be operating over Diyala. (Egypt and Israel both have F-4s but have far more modern and capable strike aircraft and are not known to be operating against ISIS.)
In July there were reports from IISS that Iraq's "new" Su-25s had Iranian tail codes, and there are reports of Iranian advisers in Diyala, which borders Iran.
