Add navigation for products on modified oscommerce

On this site, the ability to navigate to the previous/next product should be added.

[login to view URL]

Narrow arrows on the left and the right side of the body, seem the best place for this.

Maybe in a long box the same color as the menu background and black arrows?

What do you suggest?
