// Salesforce - Developer - Security - Mixed Content:

To guard against this problem, always use Salesforce to host external static 
resources, and always use HTTPS.

Salesforce provides a mechanism called "static resources" which enable you to 
upload content that you can reference inside your Visualforce pages.  This 
includes file types such as:

1. Archives (.zip and .jar)
2. Images
3. Style sheets
4. JavaScript
