So,you view the image using CV and write down the coordinates of the puzzle, put them in array and use CV to save the puzzle with different name.<p>Basically, you are cropping the image and saving it - which even a crappy cropping tool does. Do not consider this as a discouraging comment - programming can do better.<p>I understand you are looking for jobs and trying things. If I'm the hiring manager, I would rather prefer a candidate who found puzzle coordinates from the image bits/pixels and suggest cropping regions.
