?The option to delete selected photos has been done away with. ?If one has imported a few and not the rest one can¡¯t select all and press the delete button and hope that those not imported will be deleted. ?An error message crops up. ?One then has to manually delete each. ?Difficult when one has hundreds of photos.
Images that I have imported by means of Airdrop from a source like my Mac, my iPad, or my wife's iPhone all appear in Photos as part of the camera roll and are treated just the same (in terms of deletability) ?as photos taken by the iPhone itself.
Images that I transferred from my Mac using iTunes in years past cannot be removed from the iPhone in the same simple way; they have their own simple way: don¡¯t sync them. That is, turn off syncing of photos, and re-sync, or remove the particular images from those being sync¡¯d.
