I am using SEO magic plugin and according to the documentation the order of setting the og:image is supposed to be og-image.jpg → og-image.png → First image found → Default URL. Each blog post has an image at the top so I would expect that unless there is an og-image.jpg or og-image.png in the page folder the blogpost image would be set as og:image. But it doesn’t - it falls back to the default-URL.
Has anyone figured out how to correctly use SEO magic? Grateful about any pointers.
