I used to participate in PhotoShop Tennis games at the Sitepoint forums around 2002.
What is 'PhotoShop Tennis'?
"Photoshop tennis is a game played through sequential alternating photoshopping of an image.
I have made a few of my photographs into free jigsaw puzzles that can be downloaded and solved. Each puzzle is a separate .exe file and the puzzle can be saved and completed later if you don't finish it in one session. If you solve a puzzle and would like to re-solve at a later time, delete the .sav file that the program creates.
Red Rose - 154 pieces
White Rose - 117 pieces; the pieces are also rotated
