.SH "DESCRIPTION"

\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\&.

The images are in PNG format, and are created by linking to Boutell\(cqs excellent gd library\&.
.SH "ACCESS CONTROL"
