Photon and HTTPS

Hello,

I need some help. I am trying to push our site to https but I continually get mixed content errors because of the images loading from the CDN. I have searched and searched for a solution and I can see that https support is available but I cant figure out how to force it without the use of another plugin which causes more conflict.

Please tell me how do I force my photon images to load https URL’s?
