- Under Gallery Settings, set “Number of images per page” to 1.
- Then check the box for “Add hidden images.” This should display just the first thumbnail in you gallery, and when you click on it, you can navigate through them in a lightbox.
-
Then you have to remove the page navigation at the bottom of that first thumbnail. There are a couple ways to do this, but the one I used is below. Locate /plugins/nextgen-gallery/nggfunctions.php Before you make any changes, you may want to make a copy of the unmodified file for later. Find the both instances of the code below and edit.
// check for page navigation if ($maxElement > 0)
change to
// check for page navigation if
($maxElement > 1)"
This will make it so that the page navigation only kicks in if you have more than one image per page (what we set in step 1).
