Hello,
I have edited my _header.html file with <link rel="image_src" href="http://www.mysite.com/templates/base/thumb.png" /> (mysite is not the name of my site, changed for privacy purposes) and it still is not showing up when I or anybody else share the link. Is there a specific place to put this line of code to get it to work? I've cleared the caches and tried multiple locations within the header file.
Any help is appreciated.
Chris
