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

SYNOPSIS
       upsimage.cgi

           Note
           As a CGI program, this should be invoked through your web server.
           If you run it from the command line, it will either complain about
           unauthorized access or spew a PNG at you.

DESCRIPTION
       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.

ACCESS CONTROL
       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.

FILES
       hosts.conf(5)
