How can I see on Photos if the picture is already in an album?

[iMore Question]

I'm sorting out a lot of historical photos and putting them in albums. When I go back to the main Photos page, how can I tell if a particular photo is already in an album? Otherwise I could be duplicating or missing out some images.

I don't know, but unless you have thousands of pics, it shouldn't take long to see whether or not you have duplicates. Also, you can sort the pics by date.
