Can I load a photo from another app's directory?

Hello! I’m new to the AppGyver world and I have the following questions:

  1. is it possible to load and show in our AppGyver’s app, an image stored in another third party app space? I’m on iOS. I copied the path shown by a previously saved image but it doesn’t show the image in my AppGyver app.
  2. obviously I also want to save a photo taken with my AppGyver app into the space of the other app (it’s a file explorer app with ftp capabilities, that’s why I want this)
  3. bonus question: can you create an AppGyver app that can expose its files to the world via ftp (so I don’t need the point 2)?

Thanks in advance for your help.
