FYI
I've put up a first version of a webpage reviewing different
resizing/downsampling methods:
http://www.xs4all.nl/~bvdwolf/main/foto/down_sample/down_sample.htm
The relevance for scanning is that in general it is beneficial to scan at
the maximum optical resolution. That will reduce the tendency for grain
aliasing, but will usually also produce a file size that's too large for web
display. Downsizing without proper precautions will produce resampling
artifacts. The methods described allow to improve the image quality if
downsizing needs to be applied.
