If you would like to use a retina-ready logo image instead of a text-based site title, follow these steps:
- Go to Appearance > Customize > Header Image in your WordPress dashboard.
- Click Add New Image and browse for the image you would like to use for a logo.
- Be sure to click the Save & Publish button to preserve your changes.
Note: Images of exactly 640×200 pixels will be used as is. If you upload an image that is smaller or larger than this size, you will be prompted to crop it.
