Subject: | Use HTTPS for Gravatar URL if request is also using HTTPS |
If the current request is using HTTPS, then the URL to gravatar.com should also use HTTPS. This avoids warnings from the browser about serving insecure (or "mixed") content over a supposedly secure connection.
I haven't looked yet, but if this code is on GitHub, then I'll send you a pull request. Thanks for writing such a neat little plugin. You saved me a bunch of effort with this!
