How to set a image for list of posts?

[GoreStarry]

I'm using the gatsby-transformer-javascript-static-exports to query the posts list.

export const data = {
  title: 'Book1',
  date: '2017-10-04',
  cover: require('./images/img.jpg'),
}

but when I query the JsFrontmatter the value of cover will be null.
And the image required by the component will be hashed, so it can't give value by image file name directly.
Is any way to make this work? THX!
