Image Squares working same as checkbox

When we use Image Squares for control type of product features, it acts like a radio button but I want to use pictures for checkbox. is there any solution for this?
thanks

Try with change <input type="radio"> to <input type="checkbox"> and onchange=\"showHideCheckboxQuantity('{0}_{1}')\"", controlId, attributeValue.Id) in Presentation\Nop.Web\Views\Product\_ProductAttributes.cshtml.

For more reference check

  case AttributeControlType.Checkboxes:
  case AttributeControlType.ReadonlyCheckboxes:
      {
      ......
      ......
      ......
      }

section.

It doesn't work with this method.
actually I have a feature with radio action and another with checkbox action and I want to use pictures for the user options.
