  How to use
demo.html    - change "form action" to point to your script location;
index01.html - change "form action" to point to your script location,
change the 'value' of "input type=radio" to the image filename;

You can customize all .html files to look how you want them, just
do not touch form option names and the special code, surrounded 
with '%%'. Copy 'index01.html' as many times as you want 
to have more categories with different images.
