Group's photos are not shared to facebook correctlly
When a user wants to share a photo from a group's photo album to facebook, it is not shared corectlly. The correct photo and the correct title are not sent to fb corectly..
it can be facebook cache, because I tried at some photos at your site, there is no problem.
use this facebook tool:

to clear the caching of that content at facebook.
