With Puzzle you can divide any opened in Firefox image (form web or stored locally) and play puzzle.
You can start play with low level 2×2 grid (4 elements) and after completion you have the option to ramp up the difficulty, which goes all the way up to a 15×15 grid.
As this is still an experimental Add-On you need a Firefox Add-on account to be able to download Puzzle. Happy Puzzling!
