Hi Ronald, libjpeg has an API for decompressing into a memory buffer. If
you download the sources (http://www.ijg.org), the docs are included.
Once it's in memory, you can draw it with the gdk_rgb*() functions.

If you want something higher level, GdkPixbuf and friends have jpeg
loaders (I think) ... not used them myself though.

HTH, John
