As long as it's under a gigabyte or so. Here are some images that may help show some problems -- colour photos tend to hide problems, partly because the eye sees the subject more easily and auto-corrects flaws, and partly because the hardest thing for rescaling is often preserving both texture and sharpness. Of course, most people are working with colour photos these days...) For potential problems with vertical artifacts, see the 1600x1200 image at http://www.fromoldbooks.org/Green-ShortHistory/pages/0187-Remains-of-Cloisters/ (I had to resize it to 1024x768 using cubic and then sharpen) The 1518x916 one at http://www.fromoldbooks.org/YouthsInstructer/pages/072-New-Post-Office-London/ has near-horizontal lines which are difficult. http://www.fromoldbooks.org/YouthsInstructer/pages/181-Dunluce-Castle/181-Dunluce-Castle-q59-1447x923.jpg has diagonals and is an RGB image instead of grayscale. http://www.fromoldbooks.org/ThomasBewick-WoodEngravings/pages/30-the-horse/1790x1307-q75.html is a fairly clean woodcut. I have some much larger images too if you want them.
