I don't know if anyone is having this strange problem, but I have seen some problems with jpegs (.jpg) being recognized by Windows Photos, and also with the free Outlook email program in relation to AI generated images.
First, .jpg images that were made with AI generated images don't get an arrow to the next, or previous, image in the Photos viewer app.
Also, the free Outlook email program is having a problem with jpeg (.jpg) attachments, as far as not recognizing them. If I delete them and try reloading them, then they seem to work.
Is anyone else noticing this?
