Adding a direct link to menu gallery

Greetings,

First, I want to add a direct link from the horizontal menu bar to link to another site. Can’t seem to get it to do that.

Also, I want some opinions on a simple HTML-based (or at least non-Flash) image gallery. I’ve tried several, but I also have problems linking the menu to them…

So basically, I have questions about linking from the menu to an off-site page.
