HTML snippet for "valid" Icon(s) on your Web page

[kshawkin]

If you validate an HTML file served over HTTPS, the HTML snippet that you are offered to embed "valid" icons in your page includes attribute values with "http://" rather than "https://" . Embedding this in your page causes Firefox and likely other browsers to complain that your page includes mixed HTTP and HTTPS content, and it the W3C Validator will not validate the page if you click on the link. I believe you can fix this by simply changing all URLs in attributes to begin with "https://".
