Please submit a file containing your products' catalog numbers and publicly-accessible image URLs. If you are planning on also updating your product data, the image URLs can be in-line with rest of the data in your main update file. You can provide up to 6 image URLs for a single product.
If you want to update a handful of images (up to 10), you can send the direct image files along with details to identify the products to [email protected].
If submitting more than 10 images, image URLs are preferred.
