A standard image thumbnail is generated by filtering and sub sampling when the blur and noise of an original image is lost since the standard thumbnails do not distinguish between high quality and low quality originals. In this paper an efficient algorithm with a blur -generating component and a noise generating component preserves the local blur and the noise of the originals. The new thumbnails are more representative of their originals for blurry images .The noise generating component
