1. Write and test a Python program that contains the following functions and allows you to create an image that is "collage" created from other images.

• initializeCollage(height, width)
  a function that returns a "blank" picture object, height pixels tall and width pixels wide
• saveCollage(collage, filename)
  a function that saves the collage as a jpeg file
• addPictureToCollage(picture, collage, x, y, scaleFactor)
  uses the pixels of the given picture to put a scaled (1.0 = same saze as original) version of the picture on the collage, with bottom left corner at column x, row y.

EXTRA SUBMISSION REQUIREMENT: In addition to the usual program code and README, you should also submit a jpg file of at least one collage created with your program.

Additional info/hints will be provided soon.

Feel free to provide addtional functions that will allow you to create much more interesting collages!
