Hi Joannis,
You thought is right: keyword is associated with pictures, so the "Related" subgrid is used to show related files. However, somehow the subgrid we see is a blank section.
Therefore, to solve it, we can edit Information form of Keyword entity and add actual subgrid of related files manually.
The original "Related" section is senseless, so we insert a subgrid below it to show related pictures, then hide the original.
Result:
(To make comparison, I didn't hide the empty section.)
