For PC users:

Mouse over a thumbnail, system will load it onto the "active image" window.

Now, mouse over the "active image" window and wait a few seconds for the loading of the magnified image.

Move the cursor around the "active image" window to view different parts of the active image.

You can roll the mouse dial to increase the magnification power from 3 to 10.

To reduce the magnification power, you need to move the mouse over any of the thumbnails, and the magnification power will be reset to 3.

For mobile phone and tab users:

The magnification power will remain at 3.

You cannot move your finger around the active image to see different parts in greater details because that action is used by the device for moving the screen around. Instead, you can tab a finger at different part of the active image, one at a time, to achieve the same result.
