I'll help you out a little:
Hints:
1.) What's an impossible name for a folder? Try Google.
2.) Try looking somewhere else in the source code.
3.) Things you might need: a number pad. Google is more helpful than you think if you're confused.
4.) Find out more about the picture.
5.) Don't let the pictures fool you. Read the sentence.
6.) Part one: Who said it? Part two: What's the tallest mountain?
7.) Sharp, major, background clue, solve the maze.
8.) There is something in the picture... find out how to reveal it.
9.) Part one: What else could a exclamation point mean? Part two: Think opposites.
