Hi,
Folders and albums within Gallery Factory are stored as a native WP custom posts. So you can develop your own theme (or extend the one you’re using) utilizing these custom post types and using Gallery Factory as a back-end. GF shortcode printout function can be called within PHP so that’s result in flawless integration.
If you’re asking about the way to do it without any programming, then unfortunately that feature is not there yet. It’s one of the priority features for the next releases (but it’ll will definitely hit the premium version first).
