C#

private void SaveImagesToFiles(Document document)
{
    DocumentRange myRange = document.CreateRange(0, 100);
    ReadOnlyShapeCollection images = document.Shapes.Get(myRange);
    if (images.Count > 0)
    {
        if (images[0].Picture != null)
        {
            DevExpress.Office.Utils.OfficeImage myImage = images[0].Picture;
            System.Drawing.Image image = myImage.NativeImage;
            string imageName = String.Format("Image_at_pos_{0}.png", images[0].Range.Start.ToInt());
            image.Save(imageName);
            System.Diagnostics.Process.Start("explorer.exe", "/select," + imageName);
        }
    }
}

VB.NET

Private Sub SaveImagesToFiles(ByVal document As Document)
    Dim myRange As DocumentRange = document.CreateRange(0, 100)
    Dim images As ReadOnlyShapeCollection = document.Shapes.[Get](myRange)

    If images.Count > 0 Then

        If images(0).Picture IsNot Nothing Then
            Dim myImage As DevExpress.Office.Utils.OfficeImage = images(0).Picture
            Dim image As System.Drawing.Image = myImage.NativeImage
            Dim imageName As String = String.Format("Image_at_pos_{0}.png", images(0).Range.Start.ToInt())
            image.Save(imageName)
            System.Diagnostics.Process.Start("explorer.exe", "/select," & imageName)
        End If

    End If
