Convert CCK fields as a single Image

I am using node profile module to provide extra fields while registration. This allows me to create a specific content type which is then integrated with the user registration page. Now after registration I want all the fields used in the registration form to be converted in a single image.

The reason I have such a requirement is because my company is selling memberships and my website has to create a jpeg image as a "Membership Card" containing the membership id, user name, address and other details (which I have created using the "node profile" module).

Any help will be appreciated.

Thanks
