【Solution】

4:3 images will automatically adapt to display as 1:1 product source samples on the cover without affecting aesthetics; 1:1 images may become distorted or partially cropped when displayed as 4:3 product source samples, potentially impacting visual appeal. Therefore, we recommend uploading 4:3 images, allowing you to choose the latest display style. For products, select the ninth style option; for news categories, choose the eighth style. If the product source format is already determined, you can upload images according to the aspect ratio of the thumbnail.
