Uploading photo from asp.net & save it to SQL

 i have used the following code for uploading photo,but dat was not working properly & in IE7 it has much more issues,like preview is not coming before uploading-
  static byte[] bydoctemp;
    static Int32 intDocLength_img = 0;
    Stream objStream_img;
 protected void bttn_upload_photo_Click(object sender, EventArgs e)
    {
        intDocLength_img = FileUpload1.PostedFile.ContentLength;

        bydoctemp = new byte[intDocLength_img];

        objStream_img = FileUpload1.PostedFile.InputStream;

        objStream_img.Read(bydoctemp, 0, intDocLength_img);


}
  private static string RandomString()
    {
        int size = 10;
&nb ...
