You might try something like:
Private Sub Picture1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Picture1.Click
Picture1.Image = Nothing
Image copyImage = Picture0.Image.Clone()
Picture1.Image = copyImage
I have not tried this. Apologies if it doesn't work.
Without something like this all of your images actually point to the same image, which is why you are having problems, I think.
Good luck! :)
