To view a file, place your mouse on that  file name and click. The file should download and display on your monitor.  With most web browsers you can right click on your mouse and select save image to download it to your local computer.  The native dimensions of each image is quite large, however, most browsers will shrink them to fit the window.  If it is difficult to read the image, you may need to view it at the full size and scroll up/down and back/forth to read.  Printing a hardcopy to paper may be a better option.
