using facebook social link in FB

Hello

I continue my tests with the social bar field.
I test it also in an other site : shanihotel.com


THis site is the same logic as parolevolee.

In the source I get exactly what's I want : a title, a description and an image.

I have unactivated the facebook links for all fields displayed in the template except one : the description which is not the Core description field.

I have an image field with a logo. This field is used for the facebook image.

But what's I get in Facebook popup is not good :

I get the title (good), the choice beetween 2 images (which are displayed in the page but not the image field I have chosen.

The description is not the good one.

Have you found any solution for using social bar for Facebook. ?

best regards

Michel
