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.
the image by declaring an unused "Image" object.
Advantage: Silently preloads the image without displaying anything.
only for those who support the "Image" object (currently NS/3, NS/4, IE/4).
