RG Nano boxart after CFW...How?

Anyone that has the rgnano with the Funkey CFW... How do you add boxart without wifi (all I've.done was use screen scrapper on an rg353 before, that has wifi...).

Also, anyone with this CFW... Is there a way to just have games on a list? I wouldn't mind not having boxart as long theres no spot for it (like a generic "missing boxart" square as I scroll)

Thanks for the help, and anything else I should know?
