Net1 Payment Module: There has been an error processing your credit card...

[BrianL]

I currently am getting the following error (also stated partially in the thread title):

There has been an error processing your credit card. Please try again.

--
I have SSL installed, cURL Proxy up and I don't know why it is not working properly. (I've spent a few days on this). The credit card is using the testing card using a 1.00$ order. I have not tried a real credit card just yet. Also I do have direct links to some images and I have considered that this may be a problem since there are both secure and non-secure items.

Here is the net1.php file I am using:
