Default using onClick to change images

I am trying to figure out how to change an image according to the value of a radio button. I have a basic script that accomplishes this if it stands alone. The problem is there are 4 groups of radio buttons on the page and I want each group to control its own picture. The script I have just hunts out the first image in the html code and changes it. I know that somehow I need to pass a location or some indicator into the function for it to determine which image to change. Any suggestions would be greatly appreciated. Below is the code I'm using now.


function display(pic)

<form name="a">
<input type="radio" name="a" value="0" onClick=display('images/arrow1.bmp')>
<input type="radio" name="b" value="1" onClick=display('images/arrow2.bmp')>
<input type="radio" name="c" value="2" onClick=display('images/arrow1.bmp')>
<img border="0" src="images/arrow1.bmp"><br>
<img src="images/default.bmp"><br>

You need to add a second parameter to your function, the index of the image to alter:
onClick=display('images/arrow1.bmp', 0)

function display(pic, index)
Each group of radio buttons controls its own indexed image, so your original group all have a second parameter of 0, the next block have a second parameter of 1 etc.
