Gallery, but also text, linkpage..

This is a quite easy question I guess, so I don´t think you need the standardised info.
I am simply wondering what is the best way to include things like a textpage for a gallerypage, or a linkpage.
Would you do this within the frame of the gallery-system, or directly on the webpages?

Say for instance you want to have your internetgallery as one section of the page, but also have some text and a linkpage - all built through the "gallery"-application. How would you go about to do this?
Lets say you want to be able to browse through these three sections through a menu.
Is this possible to do it via the "gallery"-application or do one have to make these things for the page outside the program?

I would like a way to do it in the program, so that it is all very easy and no problems for people to update.

Do you have any suggestions? I don't need anything fancy =)
Maybe it is time to fix so that one can have things like this in gallery? I think many would use it.
