to look for adding thumbnails for LinkedIn Updates via HootSuite. Currently its not supported !
I would strongly recommend to implement thubnail preview for LinkeIn network via Hootsuite. It just killing the required attention.
This is an excellent feature for our LinkedIn integration.

This is an excellent idea. I have noticed a decrease in traffic on my posts since they have not been including a thumbnail on LinkedIn. Pictures help a lot with posts.
