For each winning entry there is both a small and a large photograph. The small photographs are better for those who have a dial-up modem connection to the internet and the large ones are aimed at people with broadband.
When you click on one of the menus (eg 2005 photo menu) you will see two similar lists. Each winner on the left hand side will display a large photo. It takes a second or two to download a large photo on broadband but sometimes over a minute with dial-up.
In this context Large Photos means larger file to download to your computer. The actual size of the photograph will depend on your screen resolution. The large photos won't quite fit on the screen vertically if your screen has a resolution of only 800 x 600 pixels.
These large photos are impressive so if you find one you like in the "small" section then try the large version. The landscape format photos look best of all because computer screens are that shape.
The slightly ammended commentary below the photograph is is derived from that which has already appeared or will soon appear in the WFS magazine.
