You may notice that in some cases, the banner you add to a sale event is not showing when looking at your shop items.
Why is this happening?
The reason is that Etsy is creating a square thumbnail to show in the shop view. To create the square, they crop the middle of the image, leaving the top and bottom out of the customer’s view.
How can you cope with it?
To ensure that the banner is shown in the shop view as well, it is better to upload a main image that is more wide than tall. The best ratio would be about 1:0.9. This means that if the image is 1000 pixels wide, it should be about 900 pixels tall.
