Loaded appcenter.elementary.io and looked for images for apps in AppCenter, images do not load in Chromium browsers (probably others too but I haven't checked yet).
Issue caused by browser blocking mixed content images by default.
Expected Behavior
See thumbnail images icons for apps
Steps to Reproduce
Go to appcenter.elemenatry.io
Look for images of app icons
