Picture Box Contents

[crazymarvin]

How can you find out if a picture box contains an image or is just empty? I want to be able to use a loop to empty all my picture boxes, however if one of them doesnt contain an image i get a runtime error. Here is the code I have so far:

        Dim counter As Integer
        For counter = 1 To 9
            Dim cntrl_name As String
            cntrl_name = "picBox" & CStr(counter)
            Panel1.Controls(cntrl_name).BackgroundImage.Dispose()
        Next

Set the background-/Image = Nothing.
