Can anyone tell me the location of the gthumb default import directory in Debian with Gnome? Put another way, where does gthumb automatically import images?

My camera is successfully detected by gthumb and when I click "Import Photos" from the "File" menu, the photos are imported. But to where they're being imported, I can't figure out. If I do a global search for file-extension ".jpg" with today's date as the "date modified", I come up with nothing.

Any help would be appreciated. Thank you.
