Change Image Checkboxes Widget size when mouse over

I need a style code css for  Witgeds Image Checkboxes  for Mous over show a big image. evry code css i try is no action or the image (class default) is changes bud not by mous over.

you have a code for me is posible?

What you actually need is a JavaScript code not CSS. For that you will need to add the form to your website using Source Code method and put the JavaScript to add this behavior.

1- Create a function to modify the image size

 function big(img) {

        img.style.height ="20px"

        img.style.width ="20px"

 }

2- Place onmouseover event as an attribute to the image and add the function name as its value with the 'this' parameter (any name can be used for the function).

2- onDISABLEDmouseover="big(this)" 

Hope that answers your concern.
