Customize photo APPS on phpfox

Hello. I need to modify photo section on phpfox. I need somebody to add more filters: For example, duplicate the "category" of photos, so the final user use more filters in search. Of course it should me fully customibzable from admin cp, letting me add as much as filters I need, and give user the hability to make a more exact search. Just like into members section of phpfox, where you can add filters from admin cp and let the user find members by more filters. I want to add advanced search. Allow final user to use multiple categories and subcategories at the same time. It must be easy to use and simple, I repeat, just like member search section, and at last, it must be compatible with the oficial phpfox mobile app. Also, I would need you to share the code with me in case I lost the data. It is imperative to use that function into original mobile app of phpfox (in both devices, android and iphone)
