I right clicked on a picture frame trying to figure out if there was a way to either lock it or see the photo a little closer... but it looks like I cleared the picture. I'm not sure if the original owner of the picture still has it.
If there's no way to lock down a picture frame so the picture can't be changed by accident this way, I'd love to see one added. Unless I'm a doof and just don't know what it is.
