Thank you Mark it works now.

I tried before inject bburl in this line

PHP Code:

 $ppuserinfo['profilepicurl'] = $vbulletin->options['profilepicurl'] . '/profilepic' . $ppuserinfo['authorid'] . '_' . $ppuserinfo['profilepicrevision'] . '.gif'; 


but I couldn't figure it out, but now it works and Facebook grap the picture too ^_^
just note I not use template I added the code to the plugin that I bought from BirdOPery5 (More Open Graph Images Gold) and now I have what I want exactly.
