Say what a thumbnail is

Tell a video from a photo before you press anything.

A thumbnail is the small still picture shown in place of a video before anybody plays it.

It is one frame from the clip, with a little arrow drawn over it. Nothing is running.

Key points

What to remember

Try this

Open your photos and look for the small arrows. Every row with one is a video.
