Very obviously a PS photo. You can tell based on how blurry the nose is compared the rest of the plane. Also, the transition between the LERX and the body appears angular and unnatural.
What we need is collaborate evidence to either back it up or toss it away.
Backing it up being another photo showing the same thing. Tossing away being a photo that can be proven as the original and lacks doctoring.
Well, I do not have time to do an exhaustive search...but I see no reason why someone could not find a picture of an SU-34 at the right angle, and then PS it.
Or perhaps combine a picture of a J-15 or J-16 with an SU-34 pic.
If found, a picture at the right angle of an SU-34 could work. Something like this, but at the right angle:
You find a pic of an SU-34 at that same angle...and you probably find the basis for the picture we are seeing.
