Not sure. I have some larger jpeg files and some of them load just fine.
The files from digital photo cameras seem to work. These files are
typically 600-800 kB and around 2300x1500 pixels.
Moreover, I have also files of 45 kB size and they don't work. If you
want I can send you samples of both.

It would indeed be nice to get rid of the unnecesary dependencies on 
libjpeg and libtiff. As I am not really familiar with GDI+, I hope that
someone else knows how to fix this.
