How can you tell if a picture text originated from the sender's phone?

[AC Question]

How can you tell the person that sent you a picture through text did not originally take the picture with their phone but it was sent to them then they forwarded it on to you?

Welcome to Android Central! Download the picture, the view it in the Gallery, tap Menu, and tap Details. If the metadata wasn't deleted by a previous user, you should see information on what camera took the picture, and possibly the location.
