Photoshop's "Save for Web" desaturates my images! very bad

1

Is there any way around this?? I’ve been working on a site with a photographer’s work and they brought up to me that their photos had lower saturation than they were suposed to, I was scratching my head for some time because I never knowingly altered the saturation. This is a major pain in the ***, I’ve had to go into flash to bring up the saturation with the adjust color filter, on all of the photos, because I don’t know how to re-save these in the same way, through photoshop, without this problem. Brings saturation down by maybe %33 or so.
