Problem in converting string into bitmap |

Hi all,
Im displaying a dynamic text box of type 'file' through javascript to get the multiple input of photos.im resizing the photos(size of the photos and path is mentioned in the webconfig file) and im saving.It is working perfect for the 'file' type text box which is not dynamic.But for the dynamic 'file' type text box it creates the problem.
The problem is while resizing the photo.
The line which is bold in the below code is giving the error-("Parameter not valid").
the problem is because im trying to pass the string argument in the bitmap fns.
example.cs
protected void btnsubmit_Click1(object sender, EventArgs e)
{
try
{
lblerror.Text = "";
addRegion.Stateid = Convert.ToInt16(ddlstate.SelectedItem.Value);
addRegion.Description = txtdesc.Text.Trim();
addRegion.Type = type;
if (txtPhotopath.PostedFile.ContentLength > 0)
{
Random rnd = new Random();
Bitmap bitImg;
string maxBannerId = "";
fullHeight = Convert.ToInt32(ConfigurationManager.AppSettings["ImgFullHeight"].ToString());
fullWidth = Convert.ToInt32(ConfigurationManager.AppSettings["ImgFullWidth"].ToString());
bannerPath = ConfigurationManager.AppSettings["ImgPath"].ToString();
bannerPath = HttpContext.Current.Server.MapPath(bannerPath);
string name = txtPhotopath.PostedFile.FileName.ToString();
filename = Path.GetFileNameWithoutExtension(name);
string Extension = Path.GetExtension(name);
maxBannerId = rnd.Next().ToString();
filename = maxBannerId + filename.Replace("'", "") + Extension;
bitImg = new Bitmap(txtPhotopath.PostedFile.InputStream);
// Save full Image
if (bitImg.Width <= fullWidth && bitImg.Height <= fullHeight)
{
bitImg.Save(bannerPath + "EventImage\\" + filename);
}
else
{
// Pass Original Size of the Image
ImageResize.Width = bitImg.Width;
ImageResize.height = bitImg.Height;
// Send Resize image width & Height Image
ImageResize.FullWidth = fullWidth;
ImageResize.FullHeight = fullHeight;
imgResizeObj.path = bannerPath + "EventImage\\";
imgResizeObj.upload(txtPhotopath, "", "", maxBannerId.ToString(), "P");
}
}
resultevent = addRegion.SaveEvents();
addRegion.PhotoPaths = filename;
addRegion.IdEventMaster = resultevent;
result = addRegion.SaveEventPhotoClips();
if (txtCtrlIds.Text != "")
{
string[] AryCtrlIdD = txtCtrlIds.Text.ToString().Split('-');
int RowIdx = 0;
for (int i = 0; i < AryCtrlIdD.Length; i++)
{
if (AryCtrlIdD[i].StartsWith("D") == true)
{
if (tblLinkMaster.FindControl(Convert.ToString(AryCtrlIdD[i])).GetType() == typeof(HtmlInputFile))
{
string strName = Convert.ToString(((HtmlInputFile)tblLinkMaster.Rows[RowIdx].FindControl(Convert.ToString(AryCtrlIdD[i]))).Value);
if (strName != "")
{
Random rnd = new Random();
Bitmap bitImg;
string maxBannerId = "";
fullHeight = Convert.ToInt32(ConfigurationManager.AppSettings["ImgFullHeight"].ToString());
fullWidth = Convert.ToInt32(ConfigurationManager.AppSettings["ImgFullWidth"].ToString());
bannerPath = ConfigurationManager.AppSettings["ImgPath"].ToString();
bannerPath = HttpContext.Current.Server.MapPath(bannerPath);
string name = strName;
filename = Path.GetFileNameWithoutExtension(name);
string Extension = Path.GetExtension(name);
maxBannerId = rnd.Next().ToString();
filename = maxBannerId + filename.Replace("'", "") + Extension;
bitImg = new Bitmap(strName);
if (bitImg.Width <= fullWidth && bitImg.Height <= fullHeight)
{
bitImg.Save(bannerPath + "EventImage\\" + filename);
}
else
{
ImageResize.Width = bitImg.Width;
ImageResize.height = bitImg.Height;
ImageResize.FullWidth = fullWidth;
ImageResize.FullHeight = fullHeight;
imgResizeObj.path = bannerPath + "EventImage\\";
imgResizeObj.upload((HtmlInputFile)tblLinkMaster.Rows[RowIdx].FindControl(Convert.ToString(AryCtrlIdD[i])), "", "", maxBannerId.ToString(), "P");
}
addRegion.IdEventMaster = resultevent;
addRegion.PhotoPaths = filename.ToString();
result = addRegion.SaveEventPhotoClips();
