Why do photos that are not mine show up when I recover photos on my LG Optimus?

[AC Question]

why do photos that are not mine show up when I recover photos on my LG Optimus?

I recently ran a photo recovery on my phone using the GT Recovery app and it recovered photos that I had never seen before, photos that I never downloaded or took using the camera on my phone. How or why did that happen?
