    You're like the Bob Ross of programming, but on just a little bit of cocaine. Nonetheless, you have great videos!

    The reference kinda misleads in the syntax area but it actually clearly states in the description which is just above the syntax:
    "You can optionally pass two callbacks, the first one (required) is triggered for each file dropped when the file is loaded. The second (optional) is triggered just once when a file (or files) are dropped."
    so the first one is the main function that deals with file.. and the 2nd one is just for fun.. 🙂
    Question is how do you know which properties of the file we can access… and the syntax of calling those properties?

    Hi there! I have replicated your example; everything works except the fact that I get a strange console message when dropping the file: " 18693: Uncaught TypeError: Cannot read property '0' of undefined (the same message is repeated several times) … ? Have no Idea what is it. Do you?

    In the p5 reference, it states that the createImg function takes the src or path as an argument. In this video, we are using file.data as an argument, which looks nothing like a path I am familiar with. How does that work? Is file.data some sort of encoded URL?
