I compiled the netpbm (1mar1994) with CygWin 1.0:
<br>
<tt>
<a href=
netpbm-cygwin-1.0-bin.tgz
>
netpbm-cygwin-1.0-bin.tgz</a> 
</tt>
(gzipped tar of *.exe)

<p>
<tt><a href=rejpg.tcl>rejpg.tcl</a>:</tt>
An example thumbnailer script
(for usage, see comments in the script.
Warning: it overwrites ./index.html !)

<hr>
<p>

<tt><a href=binio.exe>binio.exe</a></tt> infile outfile
<br> copies in binary mode; either may be "-".
