Dear Sven,
When posting a link to my website (album, event) on Facebook / Google+ nothing displays, just the link. How do I configure the Gallery to add an image thumbnail/a picture to the posted link? Same as it happens eg. when you're posting a link to Youtube?
It is much more attractive if there is some linked image posted than if there is just some text.
Do I necessarily need a Facebook App and Social sharing activated?
Thanks in advance.

I share the simplest way, ie. by copying the direct link from the browser and pasting into Facebook status entry (or eg. in gmail, etc.).

I use version 3.2.0

I am aiming at something like you find attached: an image from the gallery to be displayed as link (not my logo etc. but the first image from the gallery, the one marked with a star). Is it possible?

Thank you.
I tried to upgrade in live upgrade, but I get an error, please see attached. If I re-install the event gallery from a package, is there a risk I will lose settings or data?

After the update I can only set the the main picture for the whole site (which shows always regardless which link it is directing to), but it does not reflect the contents of the particular event I am sharing although the link is behind. Can you advise how to set particular unique picture to represent each gallery of photos?
Thank you!
