How to left align Windows 7 Task Bar

When I design some graphics, I need more space on my screen and by putting the taskbar in the left and auto hiding it gives me little extra space.

Right click on the task bar and select Properties menu item.

Now, on Taskbar location on screen drop down, select Left (or where ever you want to position) and click Apply button.

The taskbar should be positioned in the left side of the screen.
