Images are the main way to draw 2D elements on screen.
To create an Image, click on the Insert Button in the Editor and select Image.
A quick way of creating an image is by right-clicking on a Texture, Sprite, or Sprite Sheet, in the Assets View, and selecting Add to Scene
Color: A simple colored quad.
Texture: A simple textured quad.
Material: A quad using a custom material. This is typically needed to handle more complex visuals, when the capabilities of the standard 2D diffuse shader are not enough.
Sprite: Draws a Sprite.
SpriteSheet: Draws a tile of a Sprite Sheet, specified by the Current Tile property.
SpriteSheet Material: Same as a SpriteSheet, but with a custom material.
Tints the Image using a color multiply.
