I also would like to see a search capability for galleries. My wildflower gallery is approaching 200 images and will just continue to grow. I’d like to be able to find all “pasqueflowers” and so would my visitors.
If there is a customer solution, I’d be wiling to make a very modest PayPal based contribution to the author. Seems possible with SQL “LIKE %keyword%” type queries on the database in a custom template.
