Invalid image aspect ratio. The aspect ratio of the image must be less than 10:1\n.
This error occurs when the shorter side of the image is too small compared to the longer side. A thin image of a cable, for example, gets too thin when we scale it down for the thumbnail view. The longer side of an image must be no more than 10 times greater than the shorter side of the image.
To resolve this error, take a diagonal picture of the product and upload the new image. This will make the product more visible when the image is scaled down.
