Panoramic images of various laboratories and work areas can be viewed by clicking on a red-bordered area from the floor plans. From any panoramic image, you can navigate to adjacent panoramas by clicking on hotspots (usually a door and indicated by the image ). Each panoramic image file is approximately 125-250 KB in size and might take up to 45 seconds to download with a 56K modem; faster downloads can normally be achieved with ISDN and cable connections.
