[Question] How to use personal picture as wallpaper

[aus9]

ok so images prove a file or folder called files does not exist ok
I just tested created a folder using root browser and it works fine for me

If you want to have this folder on your sdcard can we try it by command?
try as local user first .....then test it exists, no need for images unless you do not understand what I am saying ok?

Code:

cd /sdcard
mkdir files
ls -al
(returns longish list...scroll up to find it...if found skip next)


(if not found then maybe need root)
su
cd /sdcard
mkdir files
ls -al

2) now try repeating the earlier copy (cp) command using local user or root
and report

no need to photos unless you are confused, I have tested the local user commands in code box

good luck
