For listing images, we accept JPG and PNG image files under 5 MB in size. The maximum image dimensions allowed is 732 px wide and 800 px tall. If the image uploaded is larger than the listed dimensions, we'll proportionally reduce the image to fit within the system parameters. There is no cropping involved for listing images.
Thumbnail images, or the image shown for a listing in the search results, are standardized at a square image size (190 px X 190 px) which does require automated cropping, unless the uploaded image is already a square. To crop the image, our system will automatically use image cues to refocus the center of the image around the featured item for sale.
