'w3 validator for GitHub published HTML5 page

I have an Html5 page published on GitHub it has a anchor link which is

<a href="http://validator.w3.org/check/referer"> <img src="http://mumstudents.org/cs472/2014-09/images/w3c-html.png"
alt="html validator" /></a>

used to take to the validator page and validate the page, but since the GitHub published pages are https I keep getting error of image showing error

is there a way to make the validator accept https URLs or change the GitHub published pages to http?
