How To Get YouTube Thumbnail Images

The other day, when I was editing Jeremy’s weekly viral video roundup post, it occurred to me that it would be nice to display a thumbnail image for the post, taken from one of the videos in his review. I thought I’d write a short post to show you how to easily pull thumbnail images for a YouTube video.


How To Download A Thumbnail Image From YouTube

There are a few different ways that you can get thumbnails from a YouTube video, one of which is to use YouTube’s Video API to extract the thumbnail. YouTube API responses may contain multiple thumbnail images for a video, each of which is identified by a tag.  Creating a call to YouTube to get the video and thumbnail information can take some time and when you are like me and don’t know a think about writing code, then the API is relatively useless.  For me, I needed a simple way to pull down a thumbnail and thankfully, there is a simple way to do this.

Here is the YouTube URL format that you will need in order to view and download a thumbnail from a YouTube video:

http://img.youtube.com/vi/VIDEO_ID/#.jpg

… where for the video example above, VIDEO_ID=bQVoAWSP7k4 and # (1,2, or 3) corresponds to one of the 3 thumbnails that YouTube automatically generates.
#2, is the default thumbnail, or the one that the owner ends up choosing for their video.
Using this convention, below are the URLs and the thumbnails that I was able to pull off of YouTube for the “wedding proposal” video from Jeremy’s post.
