It does seem to me You have problems with color profiles.

What color profile was embedded in your image from the camera?

sRGB or RGB?

Did You process RAW or use the Jpeg straight from the camera?

If, like me You use a Mac, You should be aware that the Colorsync 
engine manages the appareance of even the images displayed in Safari.

This does mean the image looks different to You than on a PC without 
colour management or simply another browse, to the best of my knowledge 
Safari is still the only browser supporting color profiles, so, You can 
download Firefox, or Camino, and display the image on this browser to 
see if it does diplay differently, You can find them at:

http://www.mozilla.org/

RapidWeaver is a great little program, and is not to blame for this.

There are two ways to get rid of this, first add code on Your page 
telling the browser not to use the embedded color profile, of simply be 
sure to turn off Photoshop color management, and save whitout embedded 
color profile, by unchecking the flag in the save as dialog.

Be aware that even in this case, having the mac by default different 
color temperatures and monitor gamma from a PC, the images will look 
brighter on Your screen than on a PC.

Simply cannot understand why some people keep using PCs... ;-)

To get an idea, if You use safari, please check the difference:

this is an image I posted on a site, since the site engine 
automatically resized it, the image did loose the embedded color 
profile,
click on the image to see it real size, and see how hues and saturation 
change.

If You have Firefox, open the link and click on the image: colour and 
saturation will not change.

If You want to know more, launch the Colorsync Utility, You can find it 
in Applications\Utilities, or simply spotlight the words, and launch 
the application help, if You haven't done this before, You simply will 
be amazed from the power concealed under the bonnet of OS X, You can 
even use it to compare color profiles!

Hope this helps.

BTW, saturation may sure not be good for skin tones, but I really like 
it when it comes to airplanes and sky, I like these shots very much.
