Shows the collection of available thumbnails in the highest possible resolution.

This script shows available thumbnails of YouTube videos and streams under the video. The thumbnail previews are clickable, linking directly to the images.

This script is not intended to be used all the time. Instead, just turn it on in your userscript manager whenever you need access to the thumbnails.

Example screenshots are from videos:

What is Kdenlive? The highest resolution thumbnail is on the left hand side, it links to https://i.ytimg.com/vi/g2Q6sluqc2I/maxresdefault.jpg

Me at the zoo – one of the oldest videos on YouTube – https://i.ytimg.com/vi/jNQXAC9IVRw/hqdefault.jpg

the most important material in science – shows a bunch of different thumbnails: the custom one uploaded by the user and different thumbnails made from the video.

When a thumbnail of a particular resolution/quality isn't available, the default YouTube placeholder is used.
