The resolution of the panorama images are based on many factors, including but not limited to the image Width/Height in pixels, the dots per inch (dpi), and the file size (Kb, Mb, etc.). All panorama images you buy on myecarousel.com will download in JPEG format, at the DPI of which the file was uploaded. No image resolution is lost from the initial upload. If the DPI information is unavailable, it will not be used in this calculation of determining resolution and will be stated as so when purchasing any panorama. All hot spot images are resized and formatted to a maximum of 600 pixels in both width and height, with a DPI of 72.
