Question with Basic SRC attribute example


#1

Hi everyone! I'm literally just starting to learn HTML on here, and I have a basic question: When Codecademy gives examples (like how to make an image a hyperlink), it has the src="#"....what is that? Is the # just filler for where you should actually put a link, or does the # mean something?
Confused at day 3...
