Manual insertion of shop logo – Offer module

Hello,

I’m using offer module to add affiliate offers on my review posts, and I’ve noticed that the logo from amazon.com.br does not appear on its offers, as it does on all other affiliate deals from other shops. Somehow the automatic logo download did not work for amazon.com.br, as it did on other shops.

Is there a way to manually insert the logo on plugin folder and assign it to amazon.com.br affiliate offers?

Thank you
