Someone said in here a while back that you could render your image at thumbnail size then you won't lose too much in the jpg conversion, I only mention it cause I did this for the first time on an image I've just finished (not posted yet) and it did look much better than the usual shrink to fit in PS. It doesn't answer your question but it's a good idea. Catlin I also saved for web for the first time and got a neat size of image without much loss of quality.
