Size does matter

There is no doubt that an image's content determines how people assess the image aesthetically. Previous works have shown that image contrast, saliency features, and the composition of objects may jointly determine whether or not an image is perceived as aesthetically pleasing. In addition to an image's content, the way the image is presented may affect how much viewers appreciate it. For example, it may be assumed that a picture will always look better when it is displayed in a larger size. Is this "the-bigger-the-better" rule always valid? If not, in what situations is it invalid?
