For the SocialShare plugin, you can configure the URL associated with the facebook link as: http://www.facebook.com/share.php?u=
When I use precisely the above, it (not surprisingly) doesn't get the link right.
I think the link needs to be something like: http://www.example.com/gallary/displayimage.php?album=
where the current album and PID are filled in by environment variables, different for each picture. That's how the demo site for the plugin works at http://www.sillig.com/coppermine
, I just don't know exactly how the configuration is on that site.
How would I update the configuration fro SocialShare to include the values that change with each photo?
