imageSizes

Indicates what size images will be displayed for hotelPhotos and roomPhotos are returned when contentDetails=high. The available image sizes are: - t : Thumbnail - s : Small - b : Big - y : 500x500v - z : 1000x1000v Resolution from smallest to largest is t < s < b < y < z. If no imageSizes is specified, the t size images will be returned. If an image is missing in one size, we will try to fall back to the same image with lower resolution. (If image \"_z\" is not available, we will try to return image \"_y\", and if it is also unavailable, we will return image \"_b\", and so on.) Only one image size is allowed.
