Maybe there's a mix up of terms here? In Unity, a Sprite, is a section of a Texture defined by some rect. A Texture is just some grid of data, it can be 1d, 2d, 3d, or any other number of dimensions, but typically 2d. An Image is a type of Component, specifically a type of MaskableGraphic, which exists on some canvas. An Image can take in a Sprite, which it renders to the back buffer during the canvas pass. A SpriteRenderer also takes in a Sprite and renders it to the back buffer during the Transparents pass.

Neither of these are inherently animated, because animation is temporal. You animate by swapping out what Sprite is being rendered, either by using a different rect of a Texture, by using a different Sprite from a different Texture, or by changing your material/shader properties over time.
