Changing the Jigsaw Puzzle
You can easily paste a different picture into your System 7.5 Jigsaw Puzzle. Simply copy any PICT graphic and paste it into the open Jigsaw Puzzle application. You may receive a message telling you to increase the puzzle application's memory. The message includes a minimum recommended size.
Restoring the Jigsaw Puzzle
The changed picture is stored in the Preferences Folder in a file called "Jigsaw Picture". Dragging this file to the Trash and relaunching the Jigsaw Puzzle application returns it to the picture stored in the resource fork of the application.
This should be a map of the world unless the PICT resource has been modified using a resource editing utility like ResEdit. If this is the case, you need to remove and reinstall the "Jigsaw" application and remove the "Jigsaw Picture" preferences to return the picture to the world map.
