Broadcasting from MacBook?

I was in the middle of FaceTiming my mother when all of a sudden, a photo slideshow started playing on her TV. She connects to the TVpad using her iPhone to watch shows. Somehow, it started playing a slideshow of my photos, which had personal photos. These personal photos were deleted off of my iPhone before this occurred. iCloud, PhotoStream, and Photo Sharing was all turned off as soon as possible. I checked my iCloud account and those photos were not there as well.

The photos were only located in my iPhoto on my MacBook, in my recently deleted photos, and photos of messages shared with my SO.

I just want to know...HOW?
