Problem with image upload in 2008

hemant kaushal

MemoryStream stream = new MemoryStream(thumbnail);

            Bitmap bmp = (Bitmap)System.Drawing.Image.FromStream(stream);

i m using above code for image uploading in 2005 and it is working properly but same code is throwing exception "Parameter is not valid." on line

Bitmap bmp = (Bitmap)System.Drawing.Image.FromStream(stream);

is there any issue with 2008 or there is some other way in it.

I have no idea what you are doing...! Are you converting into bytes? What ar you trying to do..!

I m trying to create thumbnail image of uploaded image

      {
                                image = new byte\[len\];
                                updFIle.PostedFile.InputStream.Read(image, 0, len);



                                ImageUtility objImage = new ImageUtility();
                                timage = objImage.UpdateGalleryphoto(filemime, len, image, 100, 100);                                  
                               
                                filename = updFIle.FileName;
                                BL.clsAdmin obj = new BL.clsAdmin();
                                //DataTable dt = obj.uploadImage(Request.QueryString\["prop"\].ToString(), image, timage, txtCaption.Text, filename, filemime);

} updateGallery photo is function which generates the thumbnail

public byte[] UpdateGalleryphoto(String strImageType, int len, byte[] thumbnail, int height,int width)
{
byte[] Thumbpic = null;
try
{
int EH = 75; // Max height of thumbnail
int EW = 100;//= 100; // Max width of thumbnail
Thumbpic = new byte[len];
MemoryStream stream = new MemoryStream(thumbnail);
Bitmap bmp = (Bitmap)System.Drawing.Image.FromStream(stream);
int w = bmp.Width;
int h = bmp.Height;
bool bImage = false;
// Adjust hegith or width on basic of width or height whichever is greater on same ratio

            if (height >= h && width >= w)
            {
                return thumbnail;
            }

            if (h >height)
            {
                EW = (EH \* w) / h;
            }
            else
            {
                EH = (EW \* h) / w;
            }  
            
            Thumbpic = ModifyImage(thumbnail, EW, EH, strImageType, bImage);
           

        }
        catch (Exception ex)
        {
            throw ex;
        }

        return Thumbpic;

    }

above code is working in 2005 but throwing exception in 2008 at line

Bitmap bmp = (Bitmap)System.Drawing.Image.FromStream(stream);
