the applicable site configuration file (.sources.xml). This is done to prevent web access to all file
systems accessible to the host computer.

Response: the web server collects the newest JPG file on the USR: drive
of the host CR1000

http://ip_address/drive/filename.ext. The name of the desired file is determined
using the ListFiles command.
