function theme_media_gallery_media_item_lightbox in Media Gallery 7.2

Same name and namespace in other branches

1. 7 media_gallery.theme.inc \theme_media_gallery_media_item_lightbox()

Displays a media item (entity) within a lightbox.

Clicking a thumbnail within the gallery page opens a lightbox if all these conditions are met:

• The gallery node's media_gallery_format field indicates to open a lightbox.
• The colorbox jQuery plugin is available.
• The user has JavaScript enabled.

The lightbox contains some navigation functionality (including a "slideshow" link) and a <div> containing the actual content. This function themes the contents of that <div>.

When any of the conditions for opening a lightbox aren't met, the user is taken to a separate detail page instead, the contents of which are themed by theme_media_gallery_media_item_detail().
