Question

In excel, I can assign a macro to an image, with this dialog:

This results in the code:

Private Sub MyShape_Click()
    ' ...
End Sub

However, I will need to assign this macro to many different images. How can I determine which image was selected from inside my click handler, and how do I get a reference to it?

UPDATE:

Assign the same macro to all your pictures and use Application.Caller in your macro to determine the picture/shape that called it. In this case (picture/shape) Application.Caller will be of type String.

Private Sub GenericPicture_Click()
    Select Case Application.Caller
        Case "Picture 1"
            'do your work
            MsgBox "You got me"
        Case "Picture 2" 
            'do your work
        ...

    End Select 

    'Lets flip the picture that has been clicked
    With ActiveSheet.Shapes(Application.Caller)
        .Flip msoFlipHorizontal
    End With
End Sub

And you might also implement required behavior calling a sub, which implements needed processing logic, with a parameter from separate macros:

Sub Picture1_Click()
    DoWork 1
End Sub

Sub Picture2_Click()
    DoWork 2
End Sub

Sub DoWork(ByVal pic As Integer)
    'Implement your logic here
    MsgBox "Hi! I am picture" & pic
End Sub

Where Picture1_Click() and Picture2_Click() are macros that you assign to your images/shapes.
