 JPEGs and PNGs are among the most common types of static images, which are images that do not move. JPEGs often refer to photographs, whereas PNGs often refer to graphics and designs, as they support images with transparent backgrounds. The term GIF is widely used for animated images. They contain a series of images that can be displayed as an animation.

 A `p5.Framebuffer` is a surface you can draw to, similar to the main canvas. Drawing to the main canvas is like drawing on a sheet of paper. When you call `begin()` on a `p5.Framebuffer`, it's like laying a fresh sheet of paper on top of the original, which will collect any new things that get drawn. Calling `end()` on a `p5.Framebuffer` will remove that sheet again so that subsequent drawing will go right to the main canvas again.

 *Machine learning* is like teaching a computer to learn and make choices by showing it lots of examples. The code looks at the examples and creates connections, kind of like how we learn. If we want to teach it to know the difference between cats and dogs, we show it lots of pictures and tell it which ones are cats and which ones are dogs. The more examples you show the machine learning model, the better it gets. You could then show it a new picture, and it would be able to tell if it's a cat or a dog.
