Padlock appears instantly when you installed SSL certificate properly. But in some case people do blame on the SSL or hosting provider while padlock not display without knowing whether SSL is properly installed or not. In some case SSL certificate is properly installed still padlock not display.

There are two common thing you try to solve yourself for SSL problem.
1) Absolute addresses of Image URL
If image URL is used with http protocol with entire domain name such like
<img src=”http://yourdomain.com/image.jpg”>
Then you can change that to either with https URL to that image path like the following code.
<img src=”https://yourdomain.com/image.jpg”>
2) Relative addresses of Images URL
Relative addresses totally different from absolute in that case it uses the image without protocol and the domain name. so it would simply be like the following example.
<img src=”image.jpg”>.
