How big is your computer monitor? Some of the pictures don't display well for those of us with old, 17 inch monitors. For example, I have no idea what that 'training stand' would look like if I could see it all at once. Both it and the tank are 940 pixels wide. It would be more universally user friendly if the pictures were no larger than the old 640x480 format or at least 800 x 600, although most of us can handle larger larger displays now.
