Help needed !!! Gallery search

I am trying to build a website. An integral part of this website is a search engine that will find the page number or the species name in a book my boss has written (the pages of which will be on the website). Each page is a photographic plate with some text either on top or at the side.
I have tried to build the site myself but I’ve had problems working out the search engine capability. I used NextGEN Gallery plugin but couldn’t get it to work.
I am looking for help to get this problem sorted out. This will be a very high profile website with thousands of hits a day (one of the interactive books is called “The Crossley ID Guide”)
