Pictures showing up on xBox

[starcheck]

Hi all. Hoping someone can help with this. A few months ago I got my wife and son new phones, Samsung Galaxy Victory's. Now just recently, pictures that they take on their phone are showing up on my daughter's xBox. Anyone know why this is happening? Obviously they're sharing across the wifi network somehow, but is there any way to turn this off on the phones?

Yep, go to settings wireless and network-more settings-nerby devices-file share.
Turn file share off.
