Thanks!

It would be nice to show the file size under the icon and to use
a multicolumn format when practical. This could all be done with
HTML+ e.g.

    <UL PLAIN WRAP=VERT>
        <LI><A HREF="circus.gif"><FIG SRC="file_icon" ALIGN=TOP>
            <CAPTION>278104</CAPTION>file</FIG>circus.gif</A>
        ...
    </UL>

But this will have to wait until Erik gets some free time :-)

Getting the file size explicitly is perhaps less robust, but as Andy
Norman of angeftp fame is a colleague of mine, I reckon I can beef up
the code to deal with the 15 formats or so of directory listings from
different platforms, e.g. VMS FTP servers produce 3 varieties alone!
