Facebook, Twitter, LinkedIn logos showing up in my picture gallery - wth?

[AC Question]

My Samsung S7 gallery keeps filling up with logos and random lines and dots, for no reason. I keep having to delete them. What is going on here, does anyone else have this weird problem?

Welcome to Android Central! When you see those images in the gallery, check the details and see what directory they're in. They're probably cached images being used by an app, and the directory where the images are being saved doesn't have the ".nomedia" file that should be created there (which prevents images like that from showing up in your gallery).
