I am using "Meta Tags" module.
My facebook share is grabbing the wrong image.
To fix this, I have use "Open Graph: Image: " under "Meta Tags".
But I don't know what code should I add in.
I want it to be like this.
If the article A have image a_name.jpg, the meta will be
<meta property="og:image" content="http://mysite.com/images/a_name.jpg"/>
If the article B have image b_name.jpg, the meta will be
<meta property="og:image" content="http://mysite.com/images/b_name.jpg"/>
