Photo comments

Hi new to WP, so bear with me. I am looking to have a site with various galleries, each with a different type of photo. These are local history photos etc.

I want to have these photos, so that someone can view, and look at other viewers comments and then add their own comments.

But this has to be done unique to each photo, not to a gallery or to an album. i.e. each photos will have a small mini forum unique to it

10web said photo gallery can do this?, can it be done?, so i built a small dummy site with two galleries, only to find i cant prove this until i buy the full app.

Therefore can I ask if this can be done.

Final question if people comment, they must need to log in, does photo gallery cover this or if not do i need another app as well
