Sounds strange, but i was wondering about Pythonistas new script -> "import photo" option. Then i renamed my script on my mac to ".jpg" . That should open all ways to transfer the file (photo) between apps on iPhone regardless from Dropbox and Co. I sent myself an email, imported the photo into my Photo App and then created new script in Pythonista with "import photo" -> rename from jpg to py and done. Maybe someone like me stumbles over the same problem not wanting to install more apps on iphone.
