I've done work for this company before and submitted as a CMYK .jpg as they requested.  Since they are contracting me again, I suppose whatever I've done isn't too bad or they wouldn't have asked again.  They are adament about the .jpg format (I don't know why).  The language barrier is a real challenge so it's hard to say what's on their minds...LOL.  Something else I've noticed is that when I create and save an image in PS and then open it in PSP the colors are nasty to say the least.  It's just really hard to get something close to universal. 

My idea of rebooting is kicking somebody in the butt twice!
