Here's what we do....

#!usr/bin/perl

$foo = "../images/image.gif"

open(TEXT, "foo.html");
        while (<TEXT>) {        
                if( /\$foo/) {
                        s/\$foo/$foo/;
                }               
        print;
        }
        close (TEXT);
} 

        ......

foo.html

<HTML>
<IMG SRC = "$foo"> Here's my image
</HTML>

This format also allows you to put your html documents and gifs into 
secure folders
outside your http root.
