Not sure where you can find the pattern, have you tried searching for it on the internet yet, using a search engine? To super-impose it on the original picture should be easy enough in Paintshop Pro. Open the original picture, display the Layers dialog box, promote the Background (which will be the original picture) to a Layer. Then copy the jigsaw pattern and Paste it on top of the original, as another layer (Edit > Paste > As a new layer). Then Save it, which will merge the layers.
