flexfax: Making cover pages

["Keith G. Murphy" <keithmur@mindspring.com>]

I've seen this asked but never answered:

Is there a simple (non-PostScript-guru) way to incorporate graphics
and/or text into faxcover.ps in place of the default (Silicon Graphics)
stuff, while leaving the rest of the form alone?

Most specifically, how would you get there from a graphics file such as
a GIF which contains a logo?

Of course, if going the other way (incorporating the form into the logo)
is easier, that's fine too.

I emphasize, I'm extremely PostScript-ignorant.

TIA.
