How do you delete photos from an attached SD card?
I know that when importing photos from an SD card you are offered the option of deleting them from the card but that's not what I want to do. I want to be able to import them and then view them all with a view to deleting from the SD card the ones I don't want to keep. Why would I want to do this when I can easily view and then delete them on the camera itself? Because the pictures aren't large enough on the camera for me to make the correct decision each time.
I can't see a way to do this with the built-in Photos app. Is there another app which provides this functionality?
