How do hidden pictures get hidden?

[AC Question]

hidden pictures

I had no idea I had "hidden items" in my gallery. Just went into this folder through settings in gallery and a bunch if pics from months ago showed up that I had deleted from my phone. Anyone know how these could have gotten there without me knowing?

Re: hidden pictures

We're they automatically uploaded to a cloud or G+? That could be how they are seeming to reappear on the phone. Good luck!
