Always load CSS

Hello!
I notice that FG loads its own CSS only if the shortcode is inside the post.
I have a post that show himself, but also related posts using tags.
If the main post have the gallery then CSS will be load, but if the main post doesn’t have the gallery, but other in the loop yes, FG don’t load the CSS.

Question: how can I force FG to always load CSS?

Thank you very much, I use FG on all my sites 🙂
Very nice plugin
