Porfolio Permalink

Hi,

Fairly new to wordpress. and I am using the Allegiant Pro.
I want to change the permalinks of the Portfolio pictures from my home page. Right now, they are random permalinks that bring you to a 404 page. However I have created pages that I want to link directly to my pictures? How can I can this? When I try to edit the Portfolio items, it only lets me change half of the permalink.

The page I need help with: [log in to see the link]
