You need to set the AllowDrop property of the PictureBox to True. But this property doesn't show into the properties dialog. The simplest workaround is to set them into the Load event:

PictureBox1.AllowDrop = True

My February column in the UTMag (www.utmag.com) is on this topic!

>      MessageBox.Show("End drag! " + dropEffect.ToString)

>Private Sub PictureBoxDest_DragOver(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles PictureBoxDest.DragOver
