Although you can open any image with the Photos app, it is not possible to mark an image as favorite unless or until you add it in an ‘added folder’. An ‘added folder’ is a folder from where the Photos app fetches all the pictures and videos. If you have multiple images to add and mark them as a favorite, you have to first add a new folder location in the Photos app. After adding the folder, you may find images in the Photos app. Now, you should try to add the image to the Favorite album by clicking the Add to favorite button.
