Hi!

Sorry for jumping in here without knowing too much about Lab-WOW, but
I have a suggestion! (see under the below)

I disagree here: I think the problem with this approach is that the
strongest saturation increase could clip colours. Reducing the opacity
would not help with the clipped results, so you'd never be able to
recover the quality. Even if you introduce a clipping-detector that
limits the maximum intensity of the effect, you'd still have another
problem now. The detector could get stuck on a pixel or two that have
really high saturation already, and under-affect the rest of the image. 

I think the 'best' solution is still to let the user move a slider or
set an intensity counter...

BTW... Icouldn't download the script from yahoo, at
