I always did enjoy creating custom controls.

Hope you can alter the code I came up with this morning to better suit your needs.

The steps I followed were:
(1) - create a non-functioning 'radio-button' using dreamweaver's design mode.
(2) - add a state attribute
(3) - alter the state for mouse over/out/click events
(4) - redraw the radio-button, using the appropriate image for it's state.
(5) - add a couple more buttons, ensure that the mouseover/out works for the new buttons
(6) - make a function that will create and append new radio-buttons for me.
(7) - modify the onclick routine so that all radio-buttons in the group are unchecked, before checking the one that recieved the onclick notification.

Hope I haven't forgotten anything too important above.

To use the supplied code, just save in a folder that contains rb1.png, rb2.png, rb3.png, rb4.png
