Re: Swapped Images - I've recently experienced a similar issue that may be related, thus this info might help future testing. After I took gameplay photos (streamer avatar and, from a different household, family portraits) I deleted some pictures. One was a family portrait in game and some were gameplay-pics-turned-screenshots (not with C, from cameras) that looked messed up and wasted PC space.
I later noticed that the avatar and family portraits were swapped, with wrong-household images in personal inventories. (Other deleted screenshots resulted in missing in-game pictures, a brand new feature(?) for TS4.)
Sorry if some of this is extra information, but this (and more) seems extremely relevant to recent photo bugs! :D
