NAME

       wml::des::preload - Preload Images

SYNOPSIS

	#use wml::des::preload

	<preload src=<image filename> via=<trick>>

DESCRIPTION

       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:

       "src="anyimage "via=size"
	   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.

       "src="anyimage "via=js"
	   Preloads the image anyimage by using a JavaScript snippet which loads the image by declaring an unused "Image" object.

	   Advantage: Silently preloads the image without displaying anything.

	   Disadvantage: Only works for browsers with a JavaScript implementation and only for those who support the "Image" object (currently
	   NS/3, NS/4, IE/4).
