I'm not sure why you would want to specify image sizes in percentage terms?

Either you'd have to download an enormously large high resolution bitmap and
have the browser scale it down appropriately, which would simply be
infeasible for modem download, would increase the processing load on the 
browser and would imply that browser rescaling routines would need to be of
reasonable quality (and that all browsers perform such a function).

The flipside would be for the image to be sent as now, at whatever size it
was created at, and then scaled up, which invariably looks terrible, of
course.


If there is a genuine need for images to be scaled to match the text and
window size, then it would seem to me that the only solution would be for
authors to use vector graphics (which essentially implies PostScript?),
which would tend to limit the type of images which could be used, and would
greatly increase the load on the browser were it to have to incorporate a
PostScript engine.
