Attachment page image link.

Been googling for hours and come up empty handed basically im running the genesis framework and building my own theme.

The project im working on using attachment pages when you click wordpress default gallery items which is what i wanted to do.

but on the actually attachment page if you click the image again it then links to the file location and this is what i want to disable

Also if anybody knows how to add next and previous for images from the parent post to show up aswell this would be much appreciated
