Hi Mike, thanks for the reply. Now I'm just really confused...

The picture gets imported into Photoshop CS 3 no problem. I can even
save the picture and if I view it with Finder (OS X), it looks
correct.

But when I view the picture with Firefox, it looks completely
desaturated. Here's an example:

....and yet if I send this picture to a friend as an attachment and
they open it locally, the saturation is correct.

I suppose I could fix some setting in Firefox but that will only
me, not everyone who sees my pics.

Thanks,
Jason
