Namespace I used is
using System.IO;
using System.Net.Mail;
using System.Net;
using System.Text;
using System.Drawing;
using System.Drawing.Drawing2D;
using Image = System.Drawing.Image;
It's passing A generic error code in GDI+ . Please short out the problem.

Image Resizing Problem
Dec 30, 2012 05:52 AM|LINK
Hello
I am trying to resize the uplaoding image .Here's my code
if (true)
{
string filename = Path.GetFileName(FileUpload1.PostedFile.FileName);
targetPath = Server.MapPath("CarPic/" + filename);
Stream strm = FileUpload1.PostedFile.InputStream;
var targetFile = targetPath;
string path1 = "~/CarPic/" + filename;
GenerateThumbnails(0.5, strm, targetFile);
user.Photo = path1;
}
else
{
//Label1.Text = "File size not valid";
}
#region ImageCompress
private void GenerateThumbnails(double scaleFactor, Stream sourcePath, string targetPath)
{
using (var image = Image.FromStream(sourcePath))
{
// can give static width (e.g. 1024) of image as we want
var newWidth = (int)(scaleFactor * image.Width);
//You can give static height (e.g. 1024) of image as we want
var newHeight = (int)(scaleFactor * image.Height);
var thumbnailImg = new Bitmap(newWidth, newHeight);
var thumbGraph = Graphics.FromImage(thumbnailImg);
thumbGraph.CompositingQuality = CompositingQuality.HighQuality;
thumbGraph.SmoothingMode = SmoothingMode.HighQuality;
thumbGraph.InterpolationMode = InterpolationMode.HighQualityBicubic;
var imageRectangle = new Rectangle(0, 0, newWidth, newHeight);
thumbGraph.DrawImage(image, imageRectangle);
thumbnailImg.Save(targetPath, image.RawFormat);
}
}

Make sure targetPath exists and the app has sufficient permission to access the path. Make sure the image should not be used in another processing
