The applet above is downloading a series of images. When it finishes downloading, it will turn into a button which will act as a navigation button - the web page that it goes to will show the images which should be, at that point, stored in your local cache. There are several ways of adjusting the applet such as not showing the progress bar, auto-navigating, etc.
The number of images specified to download is not limited, but the parameter names must be sequentially complete. In other words, you can specify "image0" and "image2", but if you don't specify "image1", then "image2" will be ignored. Look at the source of this page for an example of how the images are specified.
Here is a link to the actual class file 'Precache.class', in case you would like to try it out for yourself. If you find it useful, send me an email at jlhider@geocites.com.
