YouTube thumbnails

Each YouTube video has 4 generated images. They are predictably formatted as follows:


http://img.youtube.com/vi/pRpeEdMmmQ0/0.jpg

http://img.youtube.com/vi/pRpeEdMmmQ0/1.jpg

http://img.youtube.com/vi/pRpeEdMmmQ0/2.jpg

http://img.youtube.com/vi/pRpeEdMmmQ0/3.jpg

The first one in the list is a full size image and others are thumbnail images. The default thumbnail image (ie. one of 1.jpg, 2.jpg, 3.jpg) is:

http://img.youtube.com/vi/<insert-youtube-video-id-here>/default.jpg

For the high quality version of the thumbnail use a url similar to this:

http://img.youtube.com/vi/<insert-youtube-video-id-here>/hqdefault.jpg

There is also a medium quality version of the thumbnail, using a url similar to the HQ:

http://img.youtube.com/vi/<insert-youtube-video-id-here>/mqdefault.jpg

For the maximum resolution version of the thumbnail use a url similar to this:

http://img.youtube.com/vi/<insert-youtube-video-id-here>/maxresdefault.jpg

All of the above urls are available over https too. Just change http to https in any of the above urls.
