Adds the video's thumbnail to the description of the video that you are currently watching.
< Feedback on Add YouTube Thumbnail to Video Description
Defer to this alternative user script that accomplishes the same task but with a more attractive implementation:
https://greasyforks.org/en/scripts/367855-youtube-com-thumbnail
nice script, but when you click the video on the side/recommendation from the watchpage it didnt display the current thumbnail
so you have to reload the page.
can you make it works without reloading the page?
