Yes, this is what I was calling “Nextgen Search Engine” and I rely heavily on this feature as well.
I agree that I would love to see this truly integrated into Nextgen Gallery, but I attempted to broach this idea in a comment on a blog post from the Nextgen Gallery website. It was moderated out of existence so, I am guessing that this will remain a plugin type feature. ?? I have attempted email contact with Alex about help (paid) this past spring about the plugins functionality, not related to the 2.0 update. The email was unanswered, so I can only assume that Alex has abandoned this plugin feature because he is no longer associated with Nextgen Gallery.
I believe that it will be upon the users of this plugin feature to update it to work with Nextgen Gallery 2.0 and above as an open source fork of Alex’s work.
I will be looking at retrofitting this plugin feature because it is a must have for my website. I am brand new with PHP programming so it will not be a quick turnaround, if at all, as there is a large learning curve to overcome. I may need to enlist paid resources to assist me with this, if I can’t do it on my own.
I am open to any advice or assistance from the Nextgen community at large to help with moving this project along.
Thanks
Scott
