Hi

I've been using system.drawing to resize jpgs for a website. Is there any method in there for progressive browser display of the image while loading? I used to optimize images in Fireworks but now want to automate the task.

Thanks Paul
Private Sub CopyToDir(ByVal dimW As Integer, ByVal dimH As Integer, ByVal destn As String)
        Dim sourceBitmap As New Bitmap(currentImage)
 
        Dim destBitmap As New Bitmap(dimW, dimH)
        destBitmap.SetResolution(72, 72)
        Dim destGraphic As Graphics = Graphics.FromImage(destBitmap)
 
        destGraphic.DrawImage(sourceBitmap, 0, 0, _
         destBitmap.Width + 1, destBitmap.Height + 1)
 
 
        destBitmap.Save(destn, ImageFormat.Jpeg)
    End Sub

"RenderProgressive Not used in GDI+ version 1.0. "

I'm sure this is because it renders progressive by default?
