Several browsers support the attributes WIDTH and
HEIGHT for tags like <IMG>. If you know the
exact with of your image, you can tell it the browser. This might
speed up the layout-engine, because the browser doesn't have to
wait for the image to be transfered.
As you usualy don't know the exact size of your images, let your stupid computer handle that tricky task by enabling the switch GETSIZE when envoking hsc
Note:: Currently, hsc only supports
PiNG and GIF images. I would have
implemented JFIF, too, if the docs I've found
wouldn't have been in Postscript. So JFIF is delayed until
the next release.
