Hello there,
i just wished the same and couldnt find it anywhere in the web, which is a mystery to me because it seems such a natural need, and i wonder that from the 11 million downloads of NGG there are not at least 1 million requesting this feature ??
With a little bit of inventiveness i now patchworked a two lines supereasy solution for myself, which should do it until Koen extended his plugin.
It only works with one searchword for the moment, at least it just ignores additional words and not leading to malfunction.
So i have just put
<?php $search_query = get_search_query();
echo do_shortcode( '[nggtags gallery=' . $search_query . ' ]' );?>
into my search.php, and it works! As result it gives back a list of thumbs of the images that are tagged with the search term.
Maybe someone can make it work even with more search terms ( i am not php enough but it should be very easy since just all spacebars have to be replaced with commas (search query gives back word1 word2 and the shortcode needs word1,word2))
So far for tonight, i also wrote to photocrati, since i really cannot believe this doesnt exist yet. Maybe in PRO or PLUS versions they have it. I’ll keep you up-to-date.
Best wishes
Sofian
