It does work. Set your settings to ordered, with single pass
colour quant. and it goes all dithery.
If you set it to ordered, two pass, the decoder defaults to
Floyd-Steinberg dithering anyway, IIRC. The best results
come from - for me - using f-s, one pass, fast integer
decoding. Higher quality colour quantization reduces the
need for dithering images.
In actual fact, it can be said that Voyager's colour quant.
routine is so good that it doesn't splatter a noisy fuzz
over each and every image it finds whether it can find the
right colours or not: like another browser we could mention ;)
Just play with the settings. And if you're using less than
256 colours then don't be surprised if the 'quality' is shit,
because it's more a factor of colour depth than quality of
algorithms. Or summink ;)
