JWebb on "Adding extra links in the menu ( breadcrumb ? )"

I would like to add some more links to the menu in my gallery ( are they called Breadcrumb ? ).

Currently I am running a slightly modified basic gallery with a menu in the format
Home> gallery>sub gallery> large image.

I would like to add some extra links to already existing html webpages. ( eg a link to my prices page and a link to my copyright page ) I did this with gallery 2 and want to achieve the same with my new zen gallery looking as close as possible to this old gallery 2 installation-

Ideally I would like the gallery link to also point at an html web page rather than the zenphoto highest level gallery.

I have the menu manager but understand this is not compatible with the basic theme and I may need to install a different theme, however non of the themes I have tried look like what I am trying to achieve. Is it possible to change the menu and stick with the basic theme?

I did a similar change with Breadcrumbs with my gallery 2 but cant find where breadcrumb is located in zen.

Unfortunately, I am only a photographer with very little experience of coding so any help is much appreciated.
