Info

YouTube stores video previews at a large size then reduces them to fit normal page listings, this script will retrieve and display the original large-sized thumbnail.

Important Note (08/31/17)

It seems YouTube has started using a new design which breaks many userscripts, here's how you can easily revert to the classic YouTube layout:
To exit the new YouTube Design layout, you can go to YouTube's homepage, click your channel icon in the top right to pop-up a menu, then click Restore classic YouTube at the bottom of its list.

If you ever want to turn the new design back on, visit https://www.youtube.com/testtube
