This include file provides the <preload> tag which can be used to
preload images. Such preloading is usually done to speedup access for following
pages. Currently there are only a few tricks how this can be done.
The following combinations are currently supported:
Preloads the image anyimage by using an <img> tag with the
attributes width=1 height=1 which leads to the loading of the image but
only to a 1 pixel in display.
Advantage: Works for all browsers.
Disadvantage: This approach has the nasty side-effect of an occuring 1 pixel
in display because width=0 height=0 does not work as expected in most
browsers (especially in Netscape 4.x). So, position your <preload>
tag somewhere it does not destroy the look and feel of your page.
