DO unlink them before anyone starts transcribing. Easy to do. Just open a photo, go to the bottom of the photo screen and click the "Link more photos" button at the bottom. This will open the linkage section and you can unlink by clicking the red (-) dash. Do them all as quickly as you can.
Then go to "MY PHOTOS" and you should be able to see which ones are still linked, in case you miss any. I don't have any in my own profile right now to show a screenshot, but I think that linked photos in that view will have a yellow (+) sign.
Reply back with the URL of the cemetery and a couple of the photos if you need more help.
