Behold is a custom image search engine which lets you search Flickr for only High Quality Images with options of images which are free to use, commercial or if they can be modified. This way you can narrow down images which are mere waste of bandwidth and waste of time.
Another option you get is to search for images which contains animals or cloud or garden etc. This is down by the way people tag the images on flickr even within it. Check out Behold
