Load images and media over HTTPS

headers.resources.mixed_passive · effort: about an hour

Why it matters

http:// images, audio and video on an https page can be swapped or watched on the network, and browsers either upgrade them or mark the page as not fully secure. Switching them to https:// URLs removes the risk and the warning.

The fix

  1. Find the http:// image, audio and video URLs (the finding lists them; the developer console flags them too).
  2. Change each to https:// after checking the file loads there, or copy the file to your own site. Look in templates, CMS content, CSS background images and srcset attributes.
