[Plugin: NextGen Gallery] Retrieving captions of images using WP search engine?

Hello
I’m delighted by the ease of use of your plugin.

BUT!!! :

how do I do to search info with the captions of the images I’ve inserted with NextGen ?

let’s imagine this… some images are inserted into a gallery.. hosted by a post.

if I search for a word contained in one of the captions related to one image, it COULD ( 🙂 ) give me as a result all the post using these images…

what can I do?

i know you’ve inserted the tag function… but… the people love to use search engines… and I do not want to put a custom google search engine and get ads in the results…

thank you for your information and your support
