I am currently working on a website and I have successfully installed my SSL certificate.
The GeoTrust SSL/TLS checker confirmed that the certificate chain (including CA) is properly installed. Everything looks fine on Chrome but my padlock is not green and on Firefox it actually states that the website is not secure because there is unencrypted elements on it.
I used an online service to check why that is and it turns out that indeed my images are not considered secure URLs. How do I deal with this situation, aka how do I embed images on my website securely?
