Changing XFCE background

[TFD]

If I right click on the Xbuntu XFCE desktop I see something about the background. But it only seems to let me select a finite set of backgrounds.. I don't see how I can add additional backgrounds, either from a web repository or from local image files.

To add additional image files to the list of selectable wallpapers click the + button below the list of images. This will open a file manager, in which you can navigate to any saved images you would like to set as your background. Just find the image you want, and click "+ Add".

Or create the directory ~/.local/share/xfce4/backdrops and put your images there and they will show up in the dialog box with the others.

Thanks for the replies nzjethro and Toz! I now have a new background.
