The following files are computer-generated images stored in a format know as "JPG" (Joint Photographic Experts Group).
The images are of a particularly high-resolution, much larger than the size of any monitor. Thus, it is best to download the files onto your computer then view them using a graphics package rather than view them in Internet Explorer.
To download a map, click it's thumbnail image once with the second mouse button, then choose "Save target as..." from the pop-up menu. Specify a location on your computer in which to store the file, then the file will download.
Once the file has downloaded you can view or print it using an appropriate graphics package (we recommend JASC Paintshop Pro).
