The issue seems to be that Facebook can't scrape your site. When I put that URL in the Facebook URL Debug tool, it fails:
developers.facebook.com/tools/debug/og/o...Falbum%3Falbumid%3D9
Can you try the following, and the rerun your page through that debug tool to see if it helps fox the issue:
* Disable any caching you have enabled
* Disable gzip compression in the Joomla Global Configuration area
* Disable any optimization plugins or extensions you have enabled
Let me know if any of that helps.
Thanks,
Alex
