Thumbnail creation is controlled by the "Image Thumbnails" option on 

Presumably on a Linux system they are saved in ~/.thumbnails (On my Windows 
system it's C:\Users\username\.thumbnails )

I just asked GIMP to create some new thumbnails of GIMP XCF files. But I
haven't been able to locate them using the Dolphin file browser.

Where are the GIMP thumbnails stored? And what's the file extension? As
far as I can tell, GIMP 2.9/2.10 seems to "forget" about whatever
thumbnails it creates just as soon as GIMP is closed. Is there a setting
in Preferences that needs to be (re)set? Is it the Document History" option?

I don't know what folders Nautilus uses and I'm not willing to install
Nautilus to find out. But if GIMP creates thumbnails (pngs?) and puts
them in a specific folder, I can ask digiKam to monitor that folder. Or
rather maybe I can copy the thumbnails over to the folders where I keep
the XCF files.
