Ah, gotcha. Yeah I know you can upload to camera roll and send from there. Was looking more for the story upload.save the pics in your camera roll and then share them to snapchat... you wont be able to add them to your story only to your friends.
Any links that may describe the process? I have an Iphone, but I also use an android tablet for flying.you can do it on android, but its a little bit complicated...
