Im migrating my website to fully HTTPS, but one problem is that my PHP based forums allow embedding of arbitrary images, often hosted on non-HTTPS sites. How do I avoid mixed-content browser warnings for this? All i can think is that I have to have a server with a PHP script which downloads the image from the original host, and then serves it under my SSL certificate, but its not ideal. Seems like this problem must have been solv
by many people already. Any advice please?
