Icons in pixmaps

Hello,

I've been playing with my new AAO for some day's now, and I like it.
Can someone please tell me how to ad new Icons to the usr/share/pixmaps.
I did find a youtube.png on the internet and want it to show up in my Desktop and Menu using sudo mousepad etc etc
A simpel Copy and Paste of the .png using the File Manager doesn't seem work.

It's probably a no-brainer, but Linux is totally new to me.

Thank You.

 

The directories in /usr/share/ are owned by 'root' ( the administrator ).
With the filemanager in it's normal use you don't have permission to write there.

( From now on I am speculating, because I do not own a 'One', so I can not test this: )

You can try to start the filemanager with root-privileges, to do that hit alt-f2 and run

sudo thunar

( sudo meaning 'do this as super-user' and thunar is the name of the filemanager )

If this works, be careful, because now you have all the power over the system.

 

Thank you Jasper!

Should have known though. Also needed the Sudo command making changes on the Desktop.
