File menu

I have a form that has a control array of pictureboxes on it. This form is the child of an MDI form. I want the user to click Open on the File menu (which is on the MDI form) and be able to open these forms multiple times (as many times as they press open). Is this possible, and if so how?

Private Sub mnuNew_Click()
Dim Newform As Form
Set Newform = New Form1
Newform.Show
End Sub

Thanks
