If you have such a feature available to you on your system, I suggest ‘zooming’ or enlarging these paintings to the max. It’s the next best thing to seeing the real deal at the Museum! Both Windows IE and Firefox have zoom features. For IE-7 (and perhaps the other versions?), it should be at the lower right-hand corner of the screen (see the percentage sign: % at lower right). For Firefox, hold down Ctrl, Delete and + all at the same time.
