Instructions

1) Activate the image by clicking on it and dragging the mouse.

2) Hit the space bar to see links to paintings and other areas of the gallery.

3)  You can magnify an area (shift key-drag mouse), or pull away from it (use the ctr key and drag mouse), but the best way to see detail is to click on a painting. 

4) Sometimes you may need to click a couple of times on an area, such as a painting, in the java window.  Give it a try a couple of times before you give up.
