Icons on the front page

Boa tarde, um favor grande por obséquio.
I want to add the icons for Multibanco, MB Way and Payshop on the footer of the front page of my website, but I can’t find them anywhere on the ‘Payment Methods’ callout box.
Obviously I have the plugin installed, and the icons do show on the checkout page, but I need to show them on the front page footer for customer suitability and perusal.
Can you help please?
Perd?o por usar Inglês mas sinto-me mais confortável para entender e me explicar neste tipo de assunto.

Antecipadamente agradecido,
