Random cartoonish images in my hidden pics folder?

[AC Question]

I deleted a bunch of it awhile but I just looked and there are a these cartoonish images back in that hidden folder. How are they ending up there? I use quickpic to hide my wedding dress images from my fiance, and this is where they are showing up. Os it the app or my phone? Kinda creepy. I also have all of these recordings that I didn't not record, there a probably 50, ranging from a few seconds to almost an hour. This is under my VZmedia folder in device storage, with the last letter .amr, help please!

Hi, what are the recordings? are they blank or contain actual sound? it could be an app behaving badly.
