EXPORT: Simply copy/backup your source image file(s) onto some external storage (e.g., a USB drive).
cp ~/.local/share/gnome-boxes/images/debian /run/media/$USER/debian.qcow2
IMPORT: Simply use the Install from File (+ menu option) in the app's window (upper-left corner).
TIP: It's important to set the correct OS when it is undetected or unknown during import or installation.
NOTE: To maintain consistency, I suggest installing the image in its place before importing it.
EXAMPLE: install /run/media/$USER/debian.qcow2 -m 744 -t ~/.local/share/gnome-boxes/images
Optional, but recommended (for the sake of consistency), is to rename it without the qcow2 extension.
