Need help adding a gallery

I am having issues integrating a gallery onto my website '[login to view URL]' I want the gallery to have categories like on the 'home' or 'services' page and then once they've clicked a category they'd be taken to a page of pics relative to that category. I just want it integrated and for you to show me what i've been doing wrong as you go. This is a really small job and is worth less than $30.
