CMYK jpeg is perfectly real and we do attempt to support it.
There are a number of issues related including the fact that the colour values
are often reversed ie we need to use 1-value rather than value. I suspect that
stephane's images have some tag which is wrong for acrobat and converting makes
them readable.
