I was looking for a way to use the image proxy only for non-https images. This addon works perfectly for that purpose. The fact that it can help serve proxied images via CDN is a great feature as well!
I installed this add-on to avoid that my image_cache folder grow and grow, when i try to searching a way to only proxy http images, my image_cache folder weight 57GB :)
Simple, effective and excellent add-on
This is an excellent resource. Like the developer, my only goal was to proxy non-SSL images to make sure my entire site was fully SSL. Thank you for saving me bandwith.
Thank you so much for creating this resource! It works without any problems. The ignore https images functionality is something I wanted for a long time.
