We have created a new social sharing mini-site, including LinkedIn. Lots of OpenGraph tags, work. We selected specific images that will be shown when shared using the meta og: image property.
Images work great on Facebook and Pinterest, but don't work properly on LinkedIn. Here is the OG image tagging:
<meta property="og:image" content="https://img.mshanken.com/d/wso/Articles/2016/ST_TheBreakers070516_1600.jpg">
But if you click on the LinkedIn icon that we set at the bottom of our page, you will be taken to a shared page that looks like it does NOT display an image: 
More weird, if you check this preview, the IS image in the source code:
<div class="image-thumbs-container">
<img src="https://media.licdn.com/media-proxy/ext?w=180&h=110&f=c&hash=q0uvWygJS2HJrhZZ2qZGdYu2Tig%3D&ora=1%2CaFBCTXdkRmpGL2lvQUFBPQ%2CxAVta5g-0R6jnhxUzw8p4aCKqEH-50hKCoaTFXP-RFTovozTPCKqZsXfeLS-xzl5HHRU4kZnLrT9AnPhFZO5KoyAfNpxi4m_ZMc" width="130" alt="Preview of the share image" data-orig-url="https://img.mshanken.com/d/wso/Articles/2016/ST_TheBreakers070516_1600.jpg" data-width="" data-height="" data-size="" data-position="1" class="active">
</div>
What do we need to do to get this image on LinkedIn shares?
