Reply To: Lightbox profile image
I think it would be possible yes. If you look at plugins/buddypress/bp-templates/your bp theme/buddypress/members/members-loop.php for example, you can see the link for the members avatar being created for the members directory page.
Most lightboxes use a data tag to identify that the link is to open in a light box, so you could overload this file and replace the href with the link to the full size avatar and add the data tag as required.
You’d then need to add the Javascript for the lightbox, probably in a plugin and together that should work.
There’s nothing off the shelf that does this though.
However that would stop the current default of clicking on the avatar taking you to the members profile. That might be a problem for you but I guess you could simple add another button to visit the members profile.
