With the Debut Theme, Shopify recommends images of 1200px to 2000px in width, and 400px to 600px in height.
Use this to determine your banner image. Sometimes your banner will look great on desktop, but less so on mobile.
Image size: Most stores require product images to be at least 500 x 500 pixels.
