Images
Add images using the Thumbnail component to allow click-to-zoom.
An example:
import Thumbnail from '@site/src/components/Thumbnail';
<Thumbnail
  src='/img/graphql/manual/schema/validation-add-check-constraint.png'
  alt='Add check constraint'
  width='700px'
/>;
- Add an 
altprop for all images describing what the image contains. - To adjust the image size, use the 
widthprop.
