Add fuel via Paypal uses mixed http/https content

[Kowh]

I'm not sure where to direct this, but the banner image provided to PayPal (http://www.spamcop.net/images/bannerlogo.jpg) isn't using https. As the rest of the page is https some browsers will display warnings about insecure (AKA mixed) content, and in the future might just block all of the insecure content by default.

Steps to reproduce:

-Login to a reporting account

-Go to http://www.spamcop.net/mcgi?action=paymenu

-Click Proceed to PayPal payment page

-Browser loads a URL starting with https://www.paypal.com

Expected behaviour:

Browser displays an icon in the address bar indicating all page elements are sent via https.

Observed behaviour:

Browser displays an icon indicating not all elements are sent via https.
