Breadcrumbs.... unlikely for me with WG photos - I do it infrequently, and am so meticulous to clean up I'm fine..... I'm more likely to cop it from the wife for photos I've saved from FaceBook, which just plop into the photos album... I do forget them at times before I shift them to more secure lodgings! And she is in the habit of grabbing my phone, unlocking it and going through photos - mainly on holidays, to send photos of the kids to herself.... I've had a couple of heart-stops there!
