+## Configuring featured images
+
+By default, featured images for the blog are uploaded to the default SilverStripe location.  
+If you prefer, you can specify a directory into which featured images will be uploaded by adding the following to your project's config:
+
+
+
+```yaml
+SilverStripe\Blog\Model\BlogPost:
+  featured_images_directory: 'blog-images'
+```
+
+replacing 'blog-images' with the name of the directory you wish to use.
