2.3. Open Recent

This menu item can be reached from the toolbox or image menus, as File->Open Rcent, or by using the keyboard shortcut Ctrl-O.

Selecting it shows a submenu with the names of files that you have opened recently in GIMP. Just choose a name with the pointer to reopen it. You can customize the number of items shown in the menu, by changing the "Open Recent Menu Size" value in the Interface page of the Preferences dialog. See the Document History dialog section for more information.
