Dim img As New Bitmap(Server.M apPath("409.gif "))

Dim height As Integer = Int(img.Height)
Dim Width As Integer = Int(img.Width)

Dim img1 As New Bitmap(img.Clon e(New RectangleF(0, 0, 300, 50), img.PixelFormat ))

img1.Dispose()
img1.Save((Serv er.MapPath("r.g if")), ImageFormat.Gif )

Try moving your Dispose() method call after the save method. Also the file names that you are using do not look consistent. At the beginning you are using 409.gif then you try saving r.gif. I am not sure what you are trying to do there.

First, move the .Dispose() after the save call as stated.
Next ImageFormat is not the same object as ImageCodecInfo. I don't know why it wants a ImageCodecInfo when there appears to be an overload of .Save(string, ImageFormat) but I would suggest trying to fix that too.
