Is it possible to change the way a checkbox is styled in the email that is sent out?

Now, in the email that is sent after a form is submitted, my checkboxes will be displayed as:

CHECKED: {*checkbox value1*}

UNCHECKED: {*checkbox value2*}

-this is if using a widget...otherwise they will display the value of the checkboxes that are checked. I would prefer to have the checkbox values always displayed...

Is there a way to have an image display instead of "CHECKED" or "UNCHECKED"? Like a green check for CHECKED and a red X for UNCHECKED...

You might want to try using Input Table Properties field which is found under the BASIC Form Elements tab.

It will display all options in the email but will have a "check" mark/icon for the selected options. Although it doesn't show the "X" mark for unchecked options, I think this is still a better choice based on your initial request.
