.SH "DESCRIPTION"
.sp
\fBupsimage\&.cgi\fR generates the graphical bars that make up the right side of the page generated by \fBupsstats.cgi\fR(8)\&. These represent the current battery charge, utility voltage, and UPS load where available\&.
.sp
The images are in PNG format, and are created by linking to Boutell\(cqs excellent gd library\&.
.SH "ACCESS CONTROL"
.sp
upsstats will only talk to \fBupsd\fR(8) servers that have been defined in your \fBhosts.conf\fR(5)\&. If it complains about "Access to that host is not authorized", check that file first\&.
