upsimage.cgi - Image-generating helper for upsstats.cgi

       upsstats will only talk to upsd(8) servers that have been defined in your hosts.conf(5). If it complains
       about "Access to that host is not authorized", check that file first.

upsimage.cgi generates the graphical bars that make up the right side of the page generated by
       upsstats.cgi(8). These represent the current battery charge, utility voltage, and UPS load where
       available.

       The images are in PNG format, and are created by linking to Boutell’s excellent gd library.

           line, it will either complain about unauthorized access or spew a PNG at you.
