I received some jpg and psd images that were generated in Mac OSX. After
converting to jpg in several flavors, some are appearing negative
(colors inverted) under Mac OSX.

I have used convert -strip -quality 85 plus some resize.

The images are here:

It seems this is a known issue for cymk jpg in OSX. Anybody knows of a
workaround?
