How to perform relative routing

[optimatex]

Hello.
In my case i have clickable image thumbs. After clicking i have to navigate to /picture/:id to show full-size picture in popup. But image thumb could be clicked from different places like www.myapp.com/people-list/ or www.myapp.com/single-person/ . So i have to use relative routing to modify current route through pushing /picture/:id into it. How can i perfome it ?
