A list of registered keywords can be found in the specification: 
https://www.w3.org/TR/html5/links.html#allowed-keywords-and-their-meanings

The use of `rel` here doesn't appear to be correct. "Gallery" doesn't 
seem to describe the relationship between the HTML document and the 
image.

Marking the link and part of a group to have custom behaviour applied 
using JS would probably be better handled using `class`.
