+.B \-http\-proxy \fIhost:port\fP
+If you must go through a proxy to connect to the web, you can specify it
+with this option, or with the \fB$http_proxy\fP or \fB$HTTP_PROXY\fP
+environment variables.

+.B \-dictionary \fIfile\fP
+Webcollage normally looks at the system's default spell-check dictionary
+to generate words to feed into the search engines. You can specify an
+alternate dictionary with this option.
+
+Note that by default, webcollage searches for images using several
+different methods, not all of which involve dictionary words, so
+using a "topical" dictionary file will not, in itself, be as effective
+as you might be hoping.

+.B \-driftnet \fI[ args ]\fP
+.BR driftnet (1)
+is a program that snoops your local ethernet for packets that look
+like they might be image files. It can be used in conjunction
+with \fIwebcollage\fP to generate a collage of what other people on
+your network are looking at, instead of a search-engine collage.
+If you have \fIdriftnet\fP installed on your $PATH, just use
+the \fI\-driftnet\fP option. You can also specify the location
+of the program like this:
+.EX
+-driftnet /path/to/driftnet
+.EE
+or, you can provide extra arguments like this:
+.EX
+-driftnet '/path/to/driftnet -extra -args'
+.EE
+Driftnet version 0.1.5 or later is required. Note that
+the \fIdriftnet\fP program requires root access, so you'll have
+to make \fIdriftnet\fP be setuid-root for this to work.
+Please exercise caution.

+.B \-directory \fIdir\fP
+Instead of searching the web for images, use the contents of
+the given directory.
