Steganography Study

I have promised to give a funny game yesterday. However, actually, it is not that easy to make the game. This game does not have a very strict rule, and it is not really a game. This game just want to give an opportunity for me and you to get more familiar with steganography. I will provide three photos below, and what you need to do is try to get back the images hidden in these photos. I will give the solutions and the program to fetch the hidden images tomorrow.
