An important part of viewing imagery online is some standard of visual accuracy. Viewing the same image on different computers usually reveals stark discrepancies, causing great variations in the appearance of the image itself. Different monitor brands, different calibrations, and different quality all contribute to the potential skewing of the original image.
Great pains are taken to produce accurate images on this site, and the grayscale below is one way of helping calibrate your monitor to increase the accuracy. The scale has 26 distinct grades from white to black, and if you don't see each as such, the paintings may not look much like the originals. Adjusting your brightness and contrast so that all 26 square panels are distinct from each other, and not clumping in any area (usually the lightest and darkest squares) will go a great deal toward improving the images. Unfortunately, color is not so easy, but running your monitor through a color calibration test (easy on Mac OSX) is the best. Many people simply are not aware of the calibrations, and are quite surprised when they successfully run them...
