Checkbox graphics

I'm designing a feedback form with graphics for a client and they require radio buttons and checkboxes with a graphical overlay (See attached). When a number is selected, the background and the number should change colour (this could be as simple as switching to another image). As only one radio button can be selected at once, if an option is already selected, and another option is chosen, the original button should revert back to disabled colour, and the new option, active. For checkboxes, many options can be chosen. Also, it would be helpful when someone clicked the Reset form button, that all checkboxes are disabled. I require the HTML code for a row of 10 graphic checkboxes, and the code (Javascript?) required to change the image depending on the chosen selection. I will provide the checkbox graphics. I don't imagine this is a particularly hard task - I just don't have the technical know-how. Thanks, Mark
