I can see two solutions to using large images and getting the viewing
size correct for different viewers.

For the viewer, you could take Larry's advice one step further and
save the image to local disk after loading it on a page by itself.
Then the person viewing the image could use a local image manipulation
tool (I use xv, but Photoshop or something similar wold work) could
scale the image to match their viewing conditions.  I admit that this
is probably a hassle, but it is the only solution that will ensure
that every viewer sees the image at that viewer's optimal size
(regardless of whether or not a viewing aid is used).

For the webpage author, another option would be to use the WIDTH HTML
tag (within the IMG tag) to specify the percentage of the browser's
window width to display the image at.  You would probably use 100%.
The individual viewer could then resize the browser window to
automatically scale the image to the proper size (for that viewer).
