I'm looking for a code/hack to enable the use of the native WordPress gallery shortcode to display just one thumbnail instead of all thumbnails in the gallery and to display the images in that gallery in a lightbox when I click that single thumbnail.
Lightbox Plus already supports WordPress galleries to show in a lightbox. So there you don't need any hacks to implement lightbox effect to the gallery.
It's just one thumbnail I want to show in my page instead of all the thumbnails in the gallery.
Is there any hack/code to do it? Any help will be appreciated.
