you can use the programs "pnmtotiffcmyk" and "convert" to convert RGB
image files (e. g. in PPM format) into CMYK-JPEGs; here are Makefile
convert $< -colorspace CMYK -density 300x300 -quality 100 $@
pnmtotiffcmyk $< > $@
These JPEGs can be read by pdftex without problems (but you might
encounter transparency problems with buggy RIPs, as recently happened).
