Through https, which is a secure protocol, all content on the page should be loaded: images and tables, scripts and everything else. If you haven't translated it, the browser will evaluate the content as unsafe. For example, a site you have a picture loaded over HTTP. The browser will warn the visitor that the website is not secure, although it has SSL. After installing the SSL certificate, the site will be accessible via http and https. To get users to https, you need to set up a redirect.
