Each YouTube video has 4 generated images. They are predictably formatted as follows: | |
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 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 standard definition version of the thumbnail, use a url similar to this: | |
http://img.youtube.com/vi/<insert-youtube-video-id-here>/sddefault.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 | |
Size notes | |
0-480x360 | |
1-120x90 | |
2-120x90 | |
3-120x90 | |
mqdefault-320x180 | |
hqdefault-480x360 | |
sddefault-640x480 | |
maxresdefault-1280x720 | |
default-120x90 | |
where hqdefault.jpg is same as 0.jpg by comparing their hash value | |
If image does not exist, youtube display a not-found image with "..." but actually, it return a 404 to the header. | |
So you may check the http response in your programming in case you need. |
