If you look carefully it's the same photo just shopped to be in different diapers. Even the tattoo is photoshopped. Look at the legs.
It's not clear whether you mean that the tattoos were inserted or are pointing out that they made a partial attempt to remove them, but I agree, it's Photoshopped, and definitely looks odd. I'm inclined to say the tattoos are real...
The skin around the tattoo on the leg does look a little lighter, but it matches the skin on the side of their torso, under their arm, above the tattoo, which tells me that's primarily the lighting, mixed with some JPEG artifacts, which will wreak all manner of havoc (though they're not bad here, by any means). On the one where the leg tattoo is missing, the lighting on their leg doesn't match the light on their torso; it's missing the highlight, the light spot where the light is bouncing off the skin, so
that's the one where they did some retouching. The leg tattoo thematically matches the other tattoos, and those match the curvature of his arms and shoulders, as well as the lighting, too well to be photoshopped, especially given the lack of uniform lighting on the one without the leg tattoo. I wouldn't expect a high-quality insertion of tattoos from whatever editor removed the leg tattoo (or failed to insert it, though I think it's removed, because if it was inserted, that means they spent an inordinate amount of time simulating accent lighting to get that highlight down the entire side of the body right, and just never finished).
That said, it's rather strange that they'd choose to remove the tattoo from only one of these images. It looks like someone had an idea to try and remove them, and did it late in the process, to a single one of the largely-finished images (as opposed to early in the process, where they could have worked on the source image—or rather, a copy of it, because you should never touch the actual source image with destructive editing—and then imported their efforts into each design they were working on), ran out of time to finish it (or realized that the complex curves and lighting on the other tattoos is tricky to deal with), and just sent it out the door, unfinished, without bothering to undo the partial tattoo removal...
It's decent work, but there are a lot of mistakes here to learn from.
I spend way too much time looking at bad Photoshop work. Can you tell?
EDIT: Looking closer, on the one where the leg tattoo is missing, there's also a little missing chunk of their leg, where the fletching (feathered tail) of the arrow on the tattoo would be. Basically where it's darn hard to get things right, as that goes almost to the edge, and you can no longer get away with just cloning the shadow from the front of the leg, if you want the curvature to look right.
Just imagine this scenario:
