Hot to set variables of a main template from a module

[debong]

Hello. I have a problem.

I'm developing a gallery module. The module manages all the addresses (URLs) by itself. So nor a breadcrumbs neither {title} knows about a path where is a user. For egz. if gallery address is www.egz.com/gallery/ and opens www.egz.com/gallery/albums/ the cmsms thinks he is at www.egz.com/gallery/ and shows the breadcrumbs, title and all other things according to it.

Is a solution for this issue? Can I set something from the module?
