Banner Image and Favicon
The Logos menu contains upload tools for both your storefront's banner and favicon (the image that displays next to your web address in a browser).
To upload your banner, click "Browse" below Banner to find an image saved to your computer. Select the file and click Open, and then click Upload in the Design Panel. Your image will be added as your store’s banner. Click Save to save the change.
To create a banner that is stretched and centered across the page in the Basic, Basic Split, Split and Liquid layouts, we recommend an image approximately 900x200 pixels. The Sidebar layout displays logos to the left of your product images, above the title and navigation areas. This layout is ideal for square logos, approximately 200x200 pixels.
Follow the same method for your store's favicon, which is the icon that displays in the web address bar when a visitor is at your store. Be sure to click "Save" after uploading your images.
