  Behold, an interesting problem – or requirement, if you will. You have a folder full of images, say dozens or hundreds. And they are of different sizes, say height of 480 or 600 or 1024 pixels, and width of 200, 320 or 9000 pixels, and you would like to copy only high-quality, large-size images out of this folder into a separate location.
