Moving photos

I right click on an image in file manager to set as background but it doesn’t work.
I also can’t move or copy an image into the background where the default background are.
How do you add new images for backgrounds?

There is a standard directory for wallpapers. Copy the desired image files to /usr/share/backgrounds/ (sudo if necessary or if you are using the GUI file browser Right-Click -> open as root).
You should then be able to set the wallpaper e. g. via nitrogen (pre-installed with AL).

Thank you.

You are welcome, glad it worked.
It would be great if you could mark this thread as solved by clicking on the little checkmark box below by first post.

Yeah, Nitrogen is the best option for setting a wallpaper.
