Naccarato's Revenge

After being defeated by TSSOJ's most valiant hackers in a typing race, Mr. Naccarato gives up and sobs to himself. Maybe typing was never meant to be his purpose. After much thought and reflection on the meaning of his life, he has a mid life crisis. Apparently playing street fighter doesn't even require a keyboard. Discovering this, Mr. Naccarato shouts in joy and gives up on stenography... to become a steganographer! He is back once more to challenge you on the 8th day of Hackathon! Steganography is the technique of hiding secret data within an ordinary, non-secret, image file. The Hacker himself has hidden 4 clues within the photo he has graciously provided above, which all lead to different links. Now, you must overcome Zero Cool's former apprentice and decode his messages to stop him from stealing Hackmas!

N.B. It may be necessary to... manipulate visuals to see them in a new light.

There is no one perfect method for colour changing, as many different methods work for different people. Try to reveal a clue in the bottom left by adjusting colour.

Beware, Os may look like 0s

P.S. Do you have ten bucks? ( ͡° ͜ʖ ͡°)...
