A header logo provides key branding for the storefront and serves as a link to return to the home page.
Add your logo through the theme editor
To access the Logo settings, go to Customize > Sections > Header > Logo
By default, Empire will display your store name as your logo. To replace it, click the Select image button and select the file you'd like to use.
Use a 200 x 80px .PNG image file. Larger images will be automatically resized to fit this constraint.
Adjust the logo size
You will also see the Max-width and Max-height sliders to help adjust the space for your logo.
