When you go to add an image for a trap record, it does not give you an option for the android photo organiser. See attached screen shot.

Kia ora, I have tried from my android and was able to attach files from my gallery, however, I see that isn’t an option for you, have you tried the camera? sometimes photos appear as little icons in the corner. I also wonder if you have considered using the trap.nz phone app? with this you can add images to the catch records at the time you add them.
