Answer:
Kaleb states, "Huh, a button and an image are basically the same thing". He is referring to UI Controls and UI Elements.
• All UI elements that are button, textInput, textLabel, dropDown, checkBox, radioButton, image, can be moved and resized
• A button and an image are both UI elements and have positions and background images
• Both can respond to the same set of events. For example, if a programmer has written an
event handler for when a button is clicked, she could write an analogous event handler to
perform the same action when an image is clicked (or even just switch the ID of the event
handler from the id of the button to the id of the image)
