The Photos App can only access photos and videos that have been imported to your iPad’s Photo Library.
Using the Files App, locate the photos that you wish to copy to the Photo Library, then…:
- For a single photo - touch-and-hold (i.e., long-touch) the corresponding photo icon; an action menu will open. From the menu select Share; the share-sheet will open. From the share-sheet options, tap Save Image.
- For multiple photos - tap the Select button at the top of the Files App Window. Select each of the photos that you intend to copy to your Photo Library; a blue tick will appear adjacent to each photo that you have selected (you can also use the Select All button). When you have selected the photos that you wish to copy to the Photo Library, tap the Share button at bottom left of the Files App Window; the share-sheet will open. From the share-sheet options, tap Save Images.
