View plugin on GitHubGatsby remark rehype images
Parses html style tags in markdown files with an src attribute pointing to a local image, uses plugin-sharp on the image and inserts the result in rehyped attribute.
You can then load it in your React Component and call gatsby-image to get all of the goodies (blur effect etc) or even apply custom styles and create galleries etc!
