issues with chapter 'Image Processing'

[tremblap]

Hello

I'll put the fruit of my diligent reading here, bugs and suggestions.

First is a bug:

    int imgWidth = myImage.width;
    int imgHeight = myImage.height;

should use the .getWidth and .getHeight methods instead. (and loadImage just above should be replaced by .load)
