How to disable picture auto-tagging

[AC Question]

I was going through my pictures in my gallery and clicked the search button, and there were a ton of "tags" already in there (food, city scapes, night life, etc.) that I didn't create. Then when I click one of the words, it actually brings up some of my pictures that actually fit this category.

My question is, how is the phone doing this? How is it applying these tags to my photos? It's odd because when I view the information of a particular picture, the tag info is empty. I have every "auto-" thing disabled... or so I think.

Thanks.
