Searching for Plugin that might help me

So i run a dog breeding site. I used wordpress to stream line my site. Okay now i had an idea kind of like design your own dog type thing. Basically the page would start with the listing of all available males pictures. When you click on one male underneath them a listing of all possible females would pop up. Then you would click on a female and underneath them would be the pictures of past litters that match them two and current litters.

Okay i added a picture to kind of show everyone what i’m thinking of.

The problem is i thought about iframes and i thought about php includes and both of these looked horrible on the page, and took forever to code. I’m hoping there’s a possible gallery plugin that can be configured into something i’m looking for. Or if anyone knows of another way to code some inserts to create this trail effect.

Thanks in advance to anyone who can hope!!
