The only time an image needs to be expanded to full size is when it is rendered to the screen becuase at that point it has to fill all of the pixels.
But images are very commonly compressed in memory using exactly the same compression you see on disc. JPG, PNG and ZIP.
In addition there are speciality image compression file formats called DXT which are used heavily to reduce texture sizes on graphics cards. See
