There are some kinds of jpeg compressions and colour paletting that QGIS 
does not understand. If you have such files, converting them with gimp 
to a more common format is the best way.

Once you have georeferenced all your images, you can create a virtual 
raster to adress them as a single layer. Off course, stitching them in 
gimp is also possible.
