Hi there! The contact widget needs to be improved on this area fast.
The captcha image is too good that even me as a human cannot figure out what the word this (see the first word from the attached image). When this happens, I will want to be able to refresh the captcha, but there's no option for me now!
If I may suggest, rather than having another button, when the user rolls over the image, there will be an overlay that says click to refresh (or whatever wording you want).
That way, at least I don't have to refresh the entire page.
