Linkedin link ignores og tags

For some reason, linkedin will not use open image tags. I tested the og tags with the facebook debugger and there were no problems. Here is the link to the page that serves to view og tags: http://jakonazivo.cz/share/1 . You will need to look at the source of this file, as its purpose is to simply serve the og tags and then redirect to the news page on the website.

Any ideas that might cause this problem with related links
