Did she snapchat this picture to someone else?

[Alanna]

I received a picture on my NONSMARTPHONE cellphone. I went to save the picture and the file name was "Snapchat-20140308031650". I asked her "my girlfriend" if she sent this to someone else and she said no and that she never sent the picture through snapchat, the picture must have saved to a folder on my phone called snapchat. She then said she had removed snapchat from her phone before the picture was taken.

Is she lieing, does snapchat do any of this? Trying to figure out if she is cheating
Alright thanks guys, turns out she sent it to her sister, and was able to confirm this with her sister. Thanks for the help.
