Otherwise - to start:
Place your pointer inside the picture.
You will see your pointer
turn into the move icon
To move in a given
direction, set your pointer just outside the middle of the
picture, hold down your left mouse button and slowly move it in the direction
you want to travel.
When you place your pointer in the very
middle of the screen, it changes to one of 2 other icons:
Zoom-in icon 
is available in the upper
centre of the picture.
Zoom-out icon 
is available in the lower
centre of the picture. To activate, move your pointer until it changes to one
of these icons and press and hold your left mouse button. As you zoom-in the
picture gets a little grainy. This is normal and if you zoom-out the clarity
will be restored
