The 'GDAL1.2.0 WIN32 Binaries' were originally not configured for JPEG
support; i know because i built them and host them.

I noticed this a couple weeks ago, and re-built GDAL with JPEG support
enabled.  It was very hard; as soon as i linked to libjpeg.lib then a
host of nasty crashes occurred with interdependencies in the various C
stdlib versions.

It took several days, but i finally solved the problems, in part by
re-building libjpeg myself.

The file 'gdal-120-ntbin.zip' currently hosted is dated 2004/4/28 and
includes JPEG support.  If JPEGs are not working for you, it's possible
that you have the older binaries, just grab the latest.
