Not sure I follow. Are you saying you cannot upload images to the Monpedia? Are you outside of beacon range? Perhaps try rereading the tutorials on the pause menu.
We can upload images just fine and I got it working but my friend did not. Sorry i'm terrible at explaining but we were having issues where taking pictures of Mons would not register them to the monpedia and poses won't register to the monstrua. It won't allow my friend to upload images to specific Mon pages and the familiarity meter isn't there (Because it doesn't unlock in the monpedia). Mine started working out of the blue one night but I have no idea how to help my friend out
