Insecure Images in /wp

Dear Basillis,

I’m sorry but I don’t understand your advice. I’m not sure what it means to add images “from the theme options.” So far as I know, all of the images on our site have been added via the media library. Neither do I understand what it would mean to “replace them.” Does that mean delete them from the media library and upload them again?

Here’s one example. Whynopadlock.com consistently says that the primary logo on the site is insecure, thus: Insecure URL: http://centerforworldmusic.org/wp-content/uploads/2014/06/logo_w_red_type_52.png

However, when I look for this item in my media library, I find it at a secure (https) address: https://centerforworldmusic.org/wp-content/uploads/2014/06/logo_w_red_type_52.png

Any further clarification and help you could provide would be appreciated.

Thanks! Lance
