Hi Robert

I have looked at this and it is reacting this way because a correct
CMYK colorspace profile has not been embedded into the jpeg file.
LiveCode, therefore, has no idea how to interpret the colors and
handles them in an almost raw state oversaturating them. Adding the
closest profile to its natural state helps, in this instance, US Web
Coated (SWOP) v2.

I've attached another source jpg to test with which has this embedded profile.
