There are Feedback buttons on each album under the heading, feel free to comment particularly if you have any information about the image or the people in it. When you select all you are able to comment on individual images and delete the ones you dont want to comment on. The maximum allowed when selecting All is five images at a time so you have to select all and delete all but five to comment on. You can do this as many times as you like to comment on more than 5 items
We are using this feature as a Crowd Sourcing of information about these images.
