How do I move a bitmap DOWN or LEFT?

Hi,

I know the code to move a bitmap to the right, which is : (Example)
Image1.Left = Image1.Left + 20
But, how do you move the object in the opposite direction, i.e. Left.

Also, to move an object upwards its
Image1.Top = Image1.Top + 10
But, how do you move the object downwards.

Any Info, I`m in the middle of making the game!!!

Move Left: SUBTRACT values from .Left
Move Right: Add values to .Left
Move Up: SUBTRACT values from .Top
Move Down: ADD values to .Top

Sub Form_Keypress
i use these keys because its simple to use the num pad controls
'up
if KeyAscii = Asc ("8") then pic.top=pic.top-10
'down
if KeyAscii = Asc("2") then pic.top=pic.top+10
'left
if KeyAscii = Asc("4") then pic.left=pic.left-10
'right
if KeyAscii = Asc("6") then pic.left=pic.left+10
