In the latest LinkedIn release, you can now add media links: files, images AND video, to your profile, under each segment. The caveat: If you had media on your profile before, you have the ability to use this now. If you did not have media on your profile before, you may not have had this portion of the update rolled out to you yet. Don’t fret, LinkedIn has you on the radar!
Feel free to take a look at my profile for examples of media in both the summary and experience sections. Here is a quick snapshot- while in Profile Edit mode, look for that square button in the middle. Once there, just add the URLs to your media rich content, and you’ve got a savvy profile featuring your great works and insights!
