i use ngg-search 0.7.0 from Alex Rabe. so that the images can be found on wordpress search. For the search function "search_for_images" from ngg-db.php is used.
Excluded images are still displayed.
I have therefore "AND exclude = 0" inserted here (function search_for_images):
// build the final query
$query = "SELECT t.*, tt.* FROM $wpdb->nggallery AS t INNER JOIN $wpdb->nggpictures AS tt ON t.gid = tt.galleryid WHERE 1=1 AND exclude=0 $search ORDER BY tt.pid ASC $limit_by";
This works but it's a hack. Maybe there's a better solution ?
And is it a general error in Nextgen Gallery or only a problem when using the plugin ?
