the flashing is a limitation of the image control. you can try smaller pictures, but if your trying to do smooth graphics you'll need to look into BitBLT (http://www.mentalis.org/apilist/BitBlt.shtml) or something along those lines. It's not my forte, or I'd drop you some pointers, sorry.

You can work around this with the [api]LockWindowUpdate[/api] API 
| Code: | | Private Declare Function LockWindowUpdate Lib "user32" (ByVal hwndLock As Long) As Long |
Works as following :
| Code: | If KeyCode = vbKeyLeft Then
LockWindowUpdate Me.hWnd
Image1.Top = Image1.Top + 50
LockWindowUpdate 0&
End If |
