    How to display an image from a media picker?

    I'm trying to display an image from a media picker. The code below is attempting to just display the image url as a string, but it returns the JSON for the media object (I think). How do I get the image url from this string using razor? And also how do I access any crops on the media object?

    <fo:block span="all">
        @if(Model.imagePropertyName != null) {
          @Model.Media("imagePropertyName", "umbracoFile")
        }
     </fo:block>
    

    Am I doing this the wrong way? Any help would be greatly appreciated.

    Hi jonok try this:

    @if(Model.imagePropertyName != null) {
           var _image = Umbraco.Media(Model.imagePropertyName);
    
          _image.GetPropertyValue("umbracoFile");
    }

    Hi Michaël, when I try that I get this error:

    The type or namespace name 'Media' does not exist in the namespace 'Umbraco' (are you missing an assembly reference?)

    Can you show me the full code of where you are calling this?

    It's from within the PDF Creator example razor file. I've modified the '[PDF] Razor Example' to display a media picker image. This is the razor code:

        <asp:content ContentPlaceHolderId="PdfContentPlaceHolder" runat="server">

            @{
              Response.ContentType = "text/xsl";
              Response.AppendHeader("X-Pdf-Render","true");
    
              // -- Uncomment this to force the browser to download the PDF.
              // Response.AppendHeader("X-Pdf-Force-Download","darren.pdf");
