Display image in ReportViewer with a parameter

Good evening, I try to display an image in a reportViewer from a send path as a parameter.

Here is my code that I insert:

public partial class PrintFiche : Form
{
public PrintFiche()
{
InitializeComponent();
}
private void PrintFiche_Load(object sender, EventArgs e)
{
reportViewer1.LocalReport.ReportPath = "D:\\workspace\\Report\\FichePersonne.rdlc";
ReportParameter lim = new ReportParameter("image",@"C:\Documents and Settings\Mes images\Échantillons d'images\Collines.jpeg", true);
reportViewer1.LocalReport.EnableExternalImages = true;
reportViewer1.LocalReport.SetParameters(new ReportParameter[] {lim} );
this.reportViewer1.RefreshReport();
}
}

But the result I get is an image in X form

what is the mistake in this code ?

then sorry dear i cant pick ur mind, and i'm using data base for storing, for simple image storing i set image data type in data base, else you can set varbinery data type for image if you want conversion before storing and retriving..:)

public string ImageToBase64(Image image, System.Drawing.Imaging.ImageFormat format)

{   using (MemoryStream ms = new MemoryStream())

 { // Convert Image to byte[]     image.Save(ms, format); byte[] imageBytes = ms.ToArray(); // Convert byte[] to Base64 String string base64String = Convert.ToBase64String(imageBytes); return base64String;

} }

Convert your image to base64 string and then pass it to your report as parameter

 and then set the Report image to this parameter.

check your data type in data base, image data type is best for showing image without converting...
