On the full featured slideshow, the visitors can enter comments to the photos.
To switch this feature on, Tick Table II-B10: Comments system.
You can configure the behaviour like: if the user must be logged in, if an email address is required, if a smileypicker is present, avatar display, moderation, notification emails, points rewards etc... Select comments in the Show settings related to: selection box on the Settings page to see all the related settings.
To show the photos that have recent comments, you can activate the ComTen widget, see the sidebar.
There is also a shortcode version for displaying the most recently commented photos.
In this example 0: system wide, 12: max 12 photos:
[wppa type="thumbs" album="#comten,0,12"][/wppa]
You can see the comments when you click on the thumbnails, they link to the slideshow.
However... It is most likely that you want the given comments to be shown together with the thumbnails. To achieve this, tick Table IV-F7: ComTen alt display and you will get this display:
[wppa type="thumbs" album="#comten,0,12"][/wppa]

My wife Tina is a very good cook. She prepared this meal for me on july 8, 2016.
It consists of perfectly cooked pork meat, nice potatoes and chicory. We call it 'witlof' (white leaf) or 'Brussels lof'. She prepared the witlof in a delicious curry based sauce.
