Looking for PHP help

[ghrowl]

I want to make a PHP adoptables site, the free one is very nice but not quite what I want..

I was wondering how hard it would be to have people click on a landscape/map picture to find different eggs from different parts of the map..

like they click on the forest and a popup appears and says you've found (picture of a green egg) (picture of another green egg) (picture of a brown egg) whatever.. and then they click on the egg they want to adopt..

can anyone help me with this?
if so please get in touch tyvm
