What is a Youtube Thumbnail?

The thumbnail is basically the cover photo that represents your video on YouTube. It is called a thumbnail because a small version of this graphic will show up in the recommended videos and other search areas of YouTube.

YouTube will automatically pick 3 frames from the video upload and let you choose one. But most creators make and upload their own to make sure it stands out and best represents what their video is about.
