The first thing you'll notice when you're inside this image is that your cursor becomes a hand icon. To move inside the this image, HOLD DOWN your left mouse button and point the hand icon in the direction you wish to move.

Hint: The hand icon drives the image slowly if held near the center of the image. The closer the hand gets to the edge of the image, the faster the image moves.
The magnifying glass with the plus symbol appears when the cursor is slightly above the center of the image. When you see this icon, HOLD DOWN your mouse button to zoom closer into the image. You can also use the + sign on your keyboard to zoom-in.
The magnifying glass with the minus symbol appears when the cursor is slightly below the center of the image. When you see this icon, HOLD DOWN your mouse button to zoom further out of the image. You can also use the - sign on your keyboard to zoom-out.
