update .. i get
Object at URL 'http://' of type 'website' is invalid because the given value 'ro_ro.utf-8' for property 'og:locale:locale' could not be parsed as type 'enum'.
i think is from my joomla language
Fixed the part with locale


i really thing that it must be added og for heght and width

This is to clarify what you can do to allow the right image to be used immediately:

If your site provides both og:image, og:image:width and og:image:height, that image *will* be used even for the first share created. Failing to provide these means that you will need to wait for our crawlers to fetch and analyze the images first.

So... i have done it like that :
$head .= "<meta property='og:image:width' content='200'/>\n";
$head .= "<meta property='og:image:height' content='200'/>\n";

200 is the minimum accepted by facebook..... chahe how you want it
and is working ..

About Facebook sharing ADVANCED settingS :

App ID is filled
Facebook Send Buttons : Yes
Facebook Root Div : No
Load Facebook JS library : No

I only use Twitter, G+ and FB sharing.

glazweb i have update the last post. take a look.
In this way when you share a new ad for the first time.. the image will be shared
at the size that you decide for all images

@catalinads
