Option Field Radio Button value field linked to large display image?

I am trying to have an Option Field Radio Button update an image inside a div. Is there a script/function that can look at the selected radio button and use the contents of the value field (image url) to update an image on the same page? I'd like to effectively accomplish something like what these guys did with the swatches: http://dev.rockgear.com/shop/custom-ladies-tee/

(it looks like they might have used conditional logic to display the images in a separate html field, but I have so many different radio buttons that it would be much more simple/scalable if there is a way to use the value field and a script)

Thanks for any help you can provide!!!

Yes, they are using HTML fields with conditional logic. That is how this would work out of the box. You are asking for a customization here. Let me see if anyone on the team has any ideas. Also, since you are a developer license holder - you can use the Priority Support Form located here:

Gotcha, it's probably due to this being related to a customization. I'll let you know if I hear back from anyone. Your worst-case you can use conditional logic with the HTML fields.

Hi acquaphoto,

You should only need to modify ".change" on this line:

[js]
$(dropdown).change(function(){

to ".click"
