Summary: See <https://discourse.phabricator-community.org/t/lightbox-not-working/1201/3>. The lightbox code is fragile and currently relies on simulating a click on the actual "<a />" tag surrounding other images in the document. This breaks the prev/next links which ignore the event because it there's no "<img />". Instead, don't simulate clicks and just call the code we want directly. Test Plan: Added several images to a page, used lightbox prev/next buttons to cycle between them. Differential Revision: https://secure.phabricator.com/D19197
