I have included opengraph tags on my page header like so:
<meta property="og:image" content="http://image1.jpg" />
<meta property="og:image" content="http://image2.jpg" />
Image 1 is also displayed in body tag and perhaps this causes image 1 to be grabbed again, producing duplicates in the Facebook Sharer. I thought only those images with og meta tags are supposed to appear. Facebook Debug Linter shows correctly only those two images. Any help?
