How can i share a Website with leaflet openstreetmap in Facebook?

[Regina Oswald]

I have some entries in a Website like this:
http://www.abhof-automat.de/node/193
I would like to share this pages in my Facebook-Page and wont Facebook to show this map in Preview.

I tried to change the meta og:image with jquery like this;

jQuery('meta[property="og:image"]').attr('content', newImageUrl);

But i don't know what to write in newImageUrl, because the map is a puzzle of some images and not a single jpeg.

Some idea?

What I do all the time is take a screenshot of the web map, then when you post the link you can choose this as the picture that goes in the post with the link:

https://www.facebook.com/Disastermapnet-LLC-824314844248534/

They still have to click the link to get to go the fully functional map but this allows your users to at least see the content of the map.

HI Ezra,

Jes now I use this opinion.
But I would like to have a direkt link to my website with more info and not only the picture of the map in facebook.
