Yes and no I guess. In a broad sense, the more data in the image, the
more a system has to work with. So a high end video card on a good
monitor can squeeze out sharper detail. Of course, the trade off is
usually a larger file.

The other point is printing - an average printer these days is probably
600dpi, with some much higher. If your images are going to be printed, the
will look worse if the scan level is lower than the dpi used to print them.

Will people be printing out your pages? Will you want the images for
something else? You can always scan then with as much detail as possible
and then use tools to reduce the size of the file by playing with the
palette, saving as a lower res image, etc. That is what I would do - it
is better to have the image scanned at a hi res so you have the data to
throw away then it is to scan at a low res and then want to make it sharper.

of course, that is one opinion.
