You miss the point... just use it to make the interface... the coding I do myself (by the way Adobe's equivalent is their Go Live suite... which is not worth the $$)... Fireworks makes
graphics simpler to update change etc... and if you are shy on DHTML/Javacript them it helps their too... which seems to be the case.
I myself am a purist and try and stay away from graphics as it slows the site down and makes updates harder.
Just think about CWhite and then you know he will need all the help he can get. ~
As for helping experienced guys just use your fav. img. editor... sponge
