If there is a time discrepancy in the photos for an unaccountable reason, the photos could be from anything, any time, imho. And I don't believe we have an answer to the time discrepancy as of yet, for reasons mentioned earlier upthread.
I admit I have difficulty with those photos, I feel too much weight was put on them in the beginning and I believe they weren't forensically examined immediately by an expert IT person to ensure they weren't photoshopped, or a photo taken of a photoshopped photo, or tampered with in some way, for time, date, whatever - because it seems such a coincidence to me that they would have photos taken of nothing special at all, imo, with a camera purchased very recently in another country that had an incorrect and never adjusted time setting, within an hour of the boy's permanent disappearance, when FD just happened to be out of town even though he was at the grandmother's for a weekend visit to assist her with her home sale and was only gone for an hour and a half or less. I perhaps wouldn't feel it was such a coincidence if photos had been taken of W sitting with their nana who was elderly, or climbing one of her trees she would soon no longer have, or riding bikes on her driveway since W was still learning how to ride, or pictured someplace nice with FGM and her home that she was soon selling, for example.
I could swear that earlier, FGM was reported to have stated that FM had taken photos with her phone, as opposed to a camera, imo.
If the fosters have lied to the CC about the WT case, it makes it difficult to believe anything they've said, for me at least.
