Your way too late on that one.

I can think of at least three completly independant and totally free
ways to do it off the top of my head.

1. As already stated, 'convert' from the ImageMagick packages.
which will also let you transform, scale, draw on, and just about
anything else you could ever want to do in a shell script.

2. the netpbm-progs toolset,  using bmptoppm and ppmtojpeg
eg.  bmptoppm one.bmp | ppmtojpeg > one.jpg
and you can slot in any of the other ppm,pbm,pgm tools you want

3. The tools from libjpeg
eg.  cjpeg one.bmp > one.jpg 

If you didnt need a batchmode usable program, then graphics packages
like: xpaint, gimp, and numerous others can all do the job as well.

and thats just the ones you will typically find already installed.
