I'm trying to share a page with og tags.
One of the tags is og:image as described in the following link:
<https://developer.linkedin.com/documents/setting-display-tags-shares>
The image I share is legal.

For some reason linkedin doesn't show the image once I'm sharing the page through 
LinkedIn Share button (although it shows the other tags' values).

My og:image tag:

meta property="og:image" content="http://mywebsite.comm/difa2fz.png"

Any idea?
