How to save image to folder

I am using webservice to call method in businesslogics(one class written in vb).I am getting inputppath and path to where i have to save image in that method.I have to create thumbnail and also i have to save original image.Means i want to save masterimage in one folder and its thumnail in different folder. I used following code

Public Function CreateThumbNails(ByVal intWidth As Integer, ByVal strInputFilePath As String, ByVal strFileName As String, ByVal strOutputFilePath As String) As String
            Dim lnWidth As Integer = intWidth
            Dim lnHeight As Integer = 100
            Dim bmpOut As System.Drawing.Bitmap = Nothing
            Try
                Dim loBMP As New Bitmap(strInputFilePath)
                Dim lnRatio As Decimal
                Dim lnNewWidth As Integer = 0
                Dim lnNewHeight As Integer = 0
                If loBMP.Width < lnWidth AndAlso loBMP.Height < lnHeight Then
                    lnNewWidth = loBMP.Width
                    lnNewHeight = loBMP.Height
                End If
                If loBMP.Width > loBMP.Height Then
                    lnRatio = CDec(lnWidth) / loBMP.Width
                    lnNewWidth = lnWidth
                    Dim lnTemp As Decimal = loBMP.Height * lnRatio
                    lnNewHeight = CInt(lnTemp)
                Else
                    lnRatio = CDec(lnHeight) / loBMP.Height
                    lnNewHeight = lnHeight
                    Dim lnTemp As Decimal = loBMP.Width * lnRatio
                    lnNewWidth = CInt(lnTemp)
                End If

                ' *** This code creates cleaner (though bigger) thumbnails and properly
                ' *** and handles GIF files better by generating a white background for
                ' *** transparent images (as opposed to black)

                bmpOut = New Bitmap(lnNewWidth, lnNewHeight)
                Dim g As Graphics = Graphics.FromImage(bmpOut)
                g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic
                g.FillRectangle(Brushes.White, 0, 0, lnNewWidth, lnNewHeight)
                g.DrawImage(loBMP, 0, 0, lnNewWidth, lnNewHeight)
                loBMP.Dispose()
                bmpOut.Save(HttpContext.Current.Server.MapPath(strOutputFilePath) + strFileName)
                bmpOut.Dispose()

                Return strOutputFilePath + strFileName
            Catch e As Exception

                Throw New Exception("ThumbNail Creation Failed")
                Return ""
            End Try
        End Function

What code i have to include to save original size image in another folder.Can anybody help?

EDIT trigger happy. you don't need to save it from the bitmap. the file is already there. just copy the file.

If I understand your question then you want to save the image from before you manipulate it to a new location on the server.

That file already exists as a file on the server. The file location of that file is passed into your function as a parameter (strInputFilePath).

The simplest thing to do would to use File.Copy() to copy the file to the desired location.
