[Beginner Tutorial] How to change Nostale's Login Background

Hello everyone, a lot of people have asked me how to change your background in the nostale login screen, so I have done a little video to explain you.
Sorry for my bad english in the video, I'm trying my best to make myself understood.

Thank you for that tutorial! Was usefull a lot <3

I have a p-server of NosTale and I want to change icons, SP's, items and maps appearance. I tried to use NosImage and nospack but that didn't worked. Anyone knows how to do that?

I would be very grateful :)
