To resize an image use the following code
where imgHeight and imgWidth is what you want to image to be
Dim oImg As System.Drawing.Image = System.Drawing.Image.FromStream(fileUpload.PostedFile.InputStream)
Dim oResized As System.Drawing.Image = New Bitmap(imgWidth, imgHeight)
Dim oGraphic As Graphics = Graphics.FromImage(oResized)
oGraphic.CompositingQuality = Drawing2D.CompositingQuality.HighQuality
oGraphic.SmoothingMode = Drawing2D.SmoothingMode.HighQuality
oGraphic.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic
Dim oRectangle As Rectangle = New Rectangle(0, 0, imgWidth, imgHeight)
oGraphic.DrawImage(oImg, oRectangle)
oResized.Save(actualPath & fileName & ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg)
oImg.Dispose()
