I'm curious how an iphone names images. my girlfriend sent me a picture named IMG_2300. Ten minutes later she sends another picture named IMG_6811. She was sending them to prove where she was. Is there any logical way this could happen if the photos were taken from the same phone? maybe one was sent from a 3rd party app and another the default messaging app? It was either an iphone 4 or 4s. any opinions would be greatly appreciated. Thanks
