Official Code Off: STAGE 1

Image Processing

You must code a program that takes in any two .jpegs of the same resolution, and combines them equally (on top of each other) into a single image of the same resolution. The output must be displayed on screen. Writing the output image to a file is unacceptable. All code will be tested with image pairs at resolutions of 10x10, 100x100, and 1000x1000.

Each contestant has 24 hours to complete. Code must be posted in this thread by 3pm eastern tomorrow.
