Hi
I tried to acheive the same functionality using the following code. Dont know the performance bottlenecks but it works ;
Dim imgToBeCropped As Image = System.Drawing.Image.FromFile("c:\mypic.jpg"
Dim bmpImage As Bitmap = New Bitmap(imgToBeCropped

Dim bmpCrop As Bitmap = New Bitmap(20, 20, bmpImage.PixelFormat
Dim grpCrop As Graphics = Graphics.FromImage(bmpCrop
Dim rectDest As Rectangle = New Rectangle(0, 0, 20, 20
grpCrop.DrawImage(bmpImage, rectDest
bmpCrop.Save("c:\mypic1.jpg", System.Drawing.Imaging.ImageFormat.Jpeg
suggest if i m commiting a serious mistake, but it works
the bes

Hi

My code works fine if I don't stream it but as soon as I add the stream it screws up and I get the error mentioned previously! Thanks for the advise

For stream, you have to watch out the syntax
You will either use
public void Save(Stream, ImageFormat)
O
public void Save(Stream, ImageCodecInfo, EncoderParameters)
In your case
outputImage.Save(io, System.Drawing.Imaging.ImageFormat.Jpeg)
Drop the "Server.MapPath(basePath + System.IO.Path.GetFileName(_FileName.Value))
