Site not fully secure

[pazdar]

Using ver. 1.5.7 ppatch 1

I noticed that I get the following screen on Firefox:

Connection Not Secure
Parts of this page are not secure (such as images)


In both configure files my page is directed to the https://www.pazdarwinery.com

In the admin configure file I have the following:

define('HTTP_CATALOG_SERVER', 'https://www.pazdarwinery.com');
define('HTTPS_CATALOG_SERVER', 'https://www.pazdarwinery.com');

The enable SSL are set to 'true'

What else do I need to change?
