I am hoping this wasn't already addressed (I have looked everywhere and couldn't find any info), but I am curious if someone could explain to me a way that I could customize the Images displayed on the screen at boot up, from being the Factory Default of the Nokia images, to maybe something with a little more "flavor"? I have seen a couple apps that change them to the Maemo.org graphics, or some Aquateen Hunger Force Graphics... but neither of those are really my style. Do I have to actually create a .deb installer that puts the images into the N810, or is there a way I can find the file housing said images, and just supplant them?
Is it possible to change these files with a GUI file manager program? I'm pretty sure the built-in file manager won't work but will any other file manager work?

You should be able to use Midnight Commander for the job. You'll need to install it, open X Terminal, become root, and then run "mc".
Midnight Commander isn't graphical, it's a console application, but it will let navigate the file system and perform file operations with arrow and function keys. You'll get to avoid typing all those "cd", "ls", and "mv" commands at least.
EmemFM2 might also do the job. I don't know if it can be run as root as I've never used it, but it's mentioned often as a more powerful file manager.
(Actually, I've never used Midnight Commander either.)
