"Give me or lead me to" information is not the best way to ask this. Saying "I've been to sites like the coral reef network, various marine reserve sites, etc, found a bunch of information, and was just wondering if anyone else had anything they recommend" would make it seem like you have done some work on your own. The question, as stated, did not.
Just because she only needs to design the brochure, doesn't mean she shouldn't know how to find the information to put in it. That is an important life skill. But thus far it seems you have given her the topic, found information for her on the topic, and are trying to find the websites where she can find the pictures. Let the girl stand on her own two feet my friend!
BTW, if you are looking for pictures to use, don't bother just going to the coral reef sites, you need to contact/look up professional underwater photographers or sites that display their work. Dive magazine/photographers are also good sources. But anyway, this should be part of her learning experience too. Otherwise, it is a hard lesson called copyright infringement.
I am assuming this might be some sort of graphic design class or something, in which case, this topic should be an important part of the lesson (for the photographers, and for her, as an artist).
BTW, Yeah, I was one of those kids who refused to "share answers" aka "to cheat," and went to the library because I had work to do, not because I liked it. If there was an assignment, and I did the work, why should I just give it away?
