From the transcript of the radio interview someone posted earlier, this is what he said about the picture:

Notice that the interviewer hadn't asked about that; he was talking about the missing purse being a telling clue. So JC offers the pic-of-a-pic as a telling clue.
What I figured out from all of this great talk of that picture, though, is that it was a pic-of-a-pic before that night! It was a pic-of-a-pic from the boss or taken that way at school, I think! (I'll tell y'all why in a sec).
I don't think JC knew that she hadn't taken the picture herself, in her bedroom sometime that day (or so). I think he thought it would make it seem like she had to be in her bedroom doing things after he left.
But I think the picture he 'received' was digital, and the pic-of-a-pic part had already happened.
Look closely at the colors and the background on the missing poster pic, which is the same one before it was made more artistic (probably really by Katelyn?):

Look at the bow in her hair, her lips, the background and the flash!
You see, she hadn't done her artistic part to it yet!!
The version shown on Nancy Grace (that y'all said you could see on his phone) is the artistic version! It's much more colorful and the face edges and background are artistically blurred.
That's after it was (digitally) altered. But that flash was on the first version. I bet the artistic version was on a memory card of some sort, and I think JC knew that. He's only pretending (imho) that she was up there finishing the artistic parts and then physically taking a picture of it. I think the pic-of-a-pic part gave him the idea to say that.
I hope I'm being clear, lol
