(Graphics Inline Format) images from within a perl script. The module itself
is available from any <a href="qna4.html">CPAN ftp site</a>, and Lincoln maintains
an informational web page at:

The <b>JPEG.pm</b> module was written by Nick Ing-Simmons expressly for use
with the Tk family of modules. It is distributed on <a href="qna4.html">CPAN</a>
in the <kbd>authors/id/NI-S/</kbd> directories as a
<kbd>Tk-JPEG-*.tar.gz</kbd> file.
