If you don't have one you don't have the comment_form plugin enabled. That is the "comment" functionality. But in that case you should not see comments on the theme either.
I do have comments on the theme and the comment_form plugin on, but no luck.
I did notice that the admin-comments.php (i think) wasn't uploaded at all, I have uploaded it and can access the page, but the link doesn't show in the tab list...
Furthermore, when I went into the setup menu, I find it wants to delete the admin-comments.php file???? What's going on?
Setup most certainly does not want to "delete" something. Current releases don't have a "admin-comments.php" within "zp-core" so that is the actual warning about the file. It does not belong there so Zenphoto warns as it could be a sneaked in whatever file.
Again, comments are powered ny the comment_form plugin which is an official one. Of course you need to enable it to see anything related.
Anyway, all is good now after re-editing the new version! I hope that means you have correctly uploaded the new version instead of hacking some core files.

This is how it should look if you have the comments_form plugin enabled: http://www.zenphoto.org/screenshots/zenphoto-admin/comments.jpg.html
Comments are a plugin as acrylian has indicated. Enable the plugin and you will have them.
I hope that means you have correctly uploaded the new version instead of hacking some core files.
