Are you sure it is not  /home/thomas/Pictures/wallpapers?  Case is
important in Ubuntu

Well that is very easy, open a terminal.  If you don't know how to do
that then click the Super key (this often has the Windows logo on it)
and type terminal in the search bar and you should see the Terminal
icon appear, click on that.  Then in the terminal type

sudo cp pictures/wallpapers/* /usr/share/backgrounds
you will be asked for your password.  Obviously if it is actually
Pictures then use that.
The command sudo tells it to use root permissions to do the cp (copy)
command and the * means all files in that directory.

The reason people are confused about why you want to do this is that
you can easily choose pictures from your wallpapers directory in the
Change Desktop Background dialog.  You have continuously failed to
explain why you don't just do that.

No-one minds you asking questions, it is the fact that you have not
explained why the previous attempts to help have not satisfied you but
just keep asking the same question again.
