Plan Image Field Type Field-specific Parameters

Looking at the CB Subs documentation, p.423 Figure 271 has led me to create a field of Plan Image type.
However, I am slightly confused by the text for the Field-specific parameters:
"This field type allows users to display their subscription plan as an image such as an award or badge to be used in conjunction with CPay. Select images for each individual plan within CPay from the plans Integrations tab followed by Plan Image tab."
The reference to CPay is confusing me. I can find no other reference to CPay.

Would I be right in assuming that the text for the Field-specific parameters could be:
"This field type allows users to display their subscription plan as an image such as an award or badge. Select images for each individual plan from the Plan Image tab on the Plans Integrations tab."?

CPay is what CBSubs used to be called, we just forgot to change it. You need to edit your plans then on the Plans Image integration tab assign an image to that plan. Then the Plans Image field can render the images. This is how we have your subscriptions showing on the left side of every post in the Kunena sidebar (using a substitution of a plans image field). Fixed the term CPay for next release.
