Wrap Image field in

This is already set up for many lightbox plugins, the image is wrapped in an anchor tag with a “rel” attribute of “lightbox” which many lightbox plugin use to attach the action.

If it’s not working with the lightbox plugin you’re using, in most cases this means you need to add a selector to the lightbox plugin’s settings that matches the images. Take a look at the image HTML for a classname on the image wrapper that you can use for that purpose.
