 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  volt-
       age, 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)
