nextgen foobox caption not showing in pinterest

not sure this is the right place for this question, I’ll try.

I am using Nextgen with Foobox
http://www.nextgen-gallery.com/adding-functionality-foobox/

Here’s the gallery I did:

http://lilouinberlin.com/lookbook/

The problem is: when I share an image of the gallery on Pinterest the caption doesn’t show.

Anybody else had this problen? I’ve tried all the sevral settings and options but nothing worked yet.

Thanks!
