If all your images are already loaded through HTTPS, congratulations, you have nothing to worry about! You can use our HTTP Image Checker tool to ascertain that. The first step is to figure out if any of your emails are loading images through HTTP. In these cases, Chrome 81 will refuse to display the image. In other cases the certificate may have expired. Often the domain in the certificate is of the hosting provider and not the client. In some cases the domain in the certificates do not match the domain serving the image. Many HTTPS servers do not have valid certificatesĪnother piece of bad news is that even though Chrome will automatically attempt to load your images through HTTPS and many servers are already configured for HTTPS, often these servers do not contain valid SSL certificates that allow them to properly serve images through HTTPS. In this case, Chrome will block all your images if they are loaded through HTTP. Other smaller Webmail providers such as Xfinity’s may not proxy images at all. The Bad News does not proxy CSS background imagesĪlthough (and Office365) proxies your images through a secure server, CSS background images are not proxied, and if you have images that are not HTTP, these will no longer show up in. Many servers are already configured for SSL, so emails containing HTTP images will still display properly since they can also be loaded via HTTPS – as long as the SSL certificates are configured properly. Therefore, even if you host your emails on a non-HTTPS server, they’ll still load with Gmail and Yahoo! Mail.īackground images not proxied and will not displayĬhrome will attempt to load HTTPS versions of HTTP imagesĪ final piece of good news is that Chrome will automatically attempt to load HTTP images through HTTPS in an attempt to fix the issue. The second bit of good news is that Gmail, Yahoo! Mail, and to an extent proxy or route your images through their own secure servers, and by doing so rewrite the URLs of HTTP images to HTTPS, bypassing the problem. Gmail and Yahoo! Mail fixes your HTTP images for you It will also help check if HTTPS alternatives are available. The first bit of good news is we have a HTTP Image Checker tool to help you diagnose if any of your images are loaded through HTTP. This “mixed content” poses a security threat that Google seeks to abolish through this planned update. In the past even though a website might be loaded via HTTPS, browsers still allowed content such as images to be loaded via HTTP in what is called “mixed content” mode. By adding a Secure Sockets Layer (SSL) certificate, information that was previously vulnerable to theft during the communication process is now encrypted. Hypertext Transfer Protocol, or HTTP, facilitates communication between web servers and your internet browser, allowing you to load and view web pages. What’s the difference between HTTPS and HTTP? The announcement was that Chrome 81 would no longer be allowing mixed content (HTTPS and HTTP) when a website is loaded via HTTPS. Google announced a Chrome update last October that largely went unnoticed in the email industry. The next version of Chrome (Chrome 81) will cause non-HTTPS images in email to not display in certain Webmail clients.
