Hi everybody,
afaik it’s been added as an option by the original author – yay!

Hi,
I managed to make it work with a dirty, dirty, dirty hack. DO IT AT YOUR OWN RISK!
If I got some spare time I’m gonna try to improve it, but in the meantime you can:

1) Set under Options > Gallery >Number of images per page:

and Add hidden images:

2) Open nggfunctions.php, around line 250 you’ll find:

if ($maxElement > 0 && $ngg_options['galHiddenImg']) {
	  		if ( ($index < $start) || ($index > ($start + $maxElement -1)) ){
				$picturelist[$key]->hidden = true;
				$picturelist[$key]->style  = ($gallery->columns > 0) ? 'style="width:' . floor(100/$gallery->columns) . '%;display: none;"' : 'style="display: none;"';
			}
  			$index++;
		}

right below add:

if ( $maxElement==-1 && $ngg_options['galHiddenImg']) {
	  		if ( ($index > 0)  ){
				$picturelist[$key]->hidden = true;
				$picturelist[$key]->style  = ($gallery->columns > 0) ? 'style="width:' . floor(100/$gallery->columns) . '%;display: none;"' : 'style="display: none;"';
			}
  			$index++;
		}

Works perfectly with shadowbox. I’m gonna try to change it per gallery, I think I should hack nggfunctions.php and shortcodes.php, plus some admin part to add an option. For example add a checkbox “Single Thumbnail” when inserting a gallery. Let me know!
