How to insert a feed into Linkedin with a beautiful picture?

Question

Facebook

There is a feed from Facebook (no pictures)
www.facebook.com/feeds/page.php?id=442121545846518&format=rss20

An example of a link in a feed
www.facebook.com/Dataved/posts/482809675111038

If you insert this feed into LinkedIn using Twitterfeed, then

1) in the title we see ampersands like
равнобедре& #x43d;ном треугольн
2) Linkedin itself loads a small image from Facebook (the one that appears in the link) and stretches it ugly - you can see an example by making friends with Egor in his updates ru.linkedin.com/in/freesoftware/
3) Join Facebook to connect with Dataved, LLC and others you may know. superfluous and unnecessary

How to get a feed with good pictures in Linkedin, maybe with the help of other services? Maybe it's better to publish the feed not through Facebook?
