External images in .rdlc data reports for winforms

I searched Google for days to show images on .rdlc datareports but still not found a solution.
I have set:
reportViewer1.LocalReport.EnableExternalImages = true;
Image properties to "External" and have set parameters value to the value property. 

 ReportParameter Path;
        Path = new ReportParameter("Path", "C:\\Test\\579569.png");
        this.reportViewer1.LocalReport.SetParameters(new ReportParameter[] { Path });

But still i get a broken image. Is there something i am missing.I am trying this in WinForms. I know this question is asked by others..but i didn't get the result that i wanted.

Thanks in advance

I know this is for an old post but it is still relevant now. I searched so much and most answers are for web sites. I was searching for c# reportviewer in a form and a local picture file.

It worked well using this:

Add the image in rdlc. set source to external set the value to File:\C:\MyPics\logo.png

if the path is stored in database, set the value to ="File:" +First(Fields!LogoFile.Value, "DataSet1")

I also added this code in my form (you can set it directly in reportviewer control's properties if you prefer) reportViewer1.LocalReport.EnableExternalImages = true;

I got results using these codes in my own project

var imagePath = new Uri(HostingEnvironment.MapPath("PATH")).AbsoluteUri;
lr.ReportPath = HostingEnvironment.MapPath("/Report/Test1.rdlc");
lr.EnableExternalImages = true;
lr.SetParameters(new ReportParameter[] { 
    new ReportParameter("Path", imagePath)
});

Firstly, you take a new Form in your project on Load event you Wright this line below:

reportViewer1.LocalReport.EnableExternalImages = true;

after that take reportViewer on that page and set smart tag of that, choose Design a new report and take an image control on it from ToolBox, set its property

Source = External

Value = file:\D:Images\Sunset.jpg

Note: Image(Sunset.jpg) saved in Images folder on D drive. You changed it according to your requirement.

The image url must be using format file:////F:\111\333.JPG

@Praveen is right. I used Server.MapPath to get the physical path of the image:

"file:///" + Server.MapPath("~/images/nokia.jpg")

and then I set reportViewer1.LocalReport.EnableExternalImages = true; as well.

Have you tried setting MIME Type property to ImageControl in the rdlc file?

Your paths in an RDLC have to be URIs, then the string you pass to the ReportParameter is the AbsolutePath (in your case file:///C:/Test/579569.png)

    Dim filepath As Uri
    filepath = New Uri("C:\Test\579569.png")

    Dim Path As ReportParameter
    Path = New ReportParameter("Path", filepath.AbsolutePath)

    Me.reportViewer1.LocalReport.SetParameters(New ReportParameter() {Path})

Excuse VB.Net code but you get the idea.
