+If you want to apply attribution to a feature image use the following YAML front matter on posts or pages. Image credits appear directly below the feature image with a link back to the original source.

 #### Thumbnails for OG and Twitter Cards
 
 Post and page thumbnails work the same way. These are used by [Open Graph](https://developers.facebook.com/docs/opengraph/) and [Twitter Cards](https://dev.twitter.com/docs/cards) meta tags found in *head.html*. If you don't assign a thumbnail the default graphic *(default-thumb.png)* is used. I'd suggest changing this to something more meaningful --- your logo or avatar are good options.
