How to get thumbnail from Youtube using youtube API

I have a youtube video link. I want to get a thumb image from this image. Is there any way to get thumb image from a youtube link by using Youtube API ?

The answer will be of-course.

Each Youtube video has 4 generated images. There are approximately as below-

http://img.youtube.com/vi/<insert-youtube-video-id-here>/0.jpg
http://img.youtube.com/vi/<insert-youtube-video-id-here>/1.jpg
http://img.youtube.com/vi/<insert-youtube-video-id-here>/2.jpg
http://img.youtube.com/vi/<insert-youtube-video-id-here>/3.jpg

The first link in the list is full image size and other links in the list are thumb images. The default image is -

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

For the high quality thumb image of the video use a link same as follow-

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

For the maximum resolution  thumb image of the video use a link as follow-

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

For the medium quality thumb image size of the video use a link same as follow -

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

For the standard quality thumb image of the video use a link as follow -

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

All of above links are available on https. Just change http to https.

You can also use the YouTube Data API (v3)  or the older YouTube API v2.0  to get thumbnail images.
