I've got a blog with social sharing activated. I've been able to get images to appear properly when someone shares a post for Facebook, Google+ and Twitter.
However, when I click to share through LinkedIn the image isn't being pulled up. It just shows a blank space where the image should show. When I look at the source code for where the image should show, it shows that the correct image is set, but the one saved on Linkedin's servers is 1x1 pixel.
Any ideas, I've tried to fix this for a few days.
<og:image>tags in the header. Also like Facebook, it will cache the image. For LinkedIn, that can be up to 7 days. So if someone else shared or you tested without an image, it won't appear because the cache. developer.linkedin.com/docs/share-on-linkedin
