        ' Find all pictures by EntityType in the Word document.
        Dim pictures As List(Of Entity) = document.FindAllItemsByProperty(EntityType.Picture, Nothing, Nothing)

        ' Iterate through the pictures and save each one as an image file.
        For i As Integer = 0 To pictures.Count - 1
            Dim image As WPicture = TryCast(pictures(i), WPicture)

            ' Use a MemoryStream to handle the image bytes from the picture.
            Using memoryStream As MemoryStream = New MemoryStream(image.ImageBytes)
                ' Define the path where the image will be saved.
                Dim imagePath As String = Path.GetFullPath("../../Image-" & i & ".jpeg")

                ' Create a FileStream to write the image to the specified path.
                Using filestream As FileStream = New FileStream(imagePath, FileMode.Create, FileAccess.Write)
                    memoryStream.CopyTo(filestream)
                End Using
