An array of objects, each one containing an image url and a title. Images are processed asynchronously and might take some time to appear in your listing. The API does not expose processing status; retrieve the property again and check its images array. For an existing listing, this array replaces the existing images. Image requirements: URL must be a valid HTTP/HTTPS URL with file extension (.jpg, .jpeg, .png, .gif, .heic, .webp), maximum 6MB per image, minimum 500px width or height, valid image MIME type, up to 50 images per listing.
