## FAQ

### Why is the maxresdefault image missing?

YouTube only generates a 1280 × 720 thumbnail when the source video was uploaded at that resolution or higher. For older or low-resolution uploads, hqdefault at 480 × 360 is the largest available.

### Can I use these thumbnails?

The image is the uploader's copyrighted work. Linking to it or using it for commentary and reference is generally fine; republishing it as your own is not.
