I guess it\'s something very straight forward but I can\'t find out how to do it. In my controller I have:

 public ViewResult ShowForm()
        {

    Try this:

    ViewBag.Logo = Url.Content("~/Content/Images/Logo.png");

    You need a ImageController to render that.

    See this:

    ASP.NET MVC3: Image loading through controller

    and this: Can an ASP.NET MVC controller return an Image?

    once you have a controller you can render as follows:

    public class ImageController{
    
    public ActionResult ShowImage(string path) 
    {
    
        return File(path);
    }
    
    }
    

    in your views:

    <img src="@Url.Action("Render","Image", new {id =1  // or path })" />

    Use Server.MapPath to get the correct path of the image. Suppose your images folder is inside the Content folder that is normally included in an MVC project. You can do something like this:

    public ViewResult ShowForm()
    {
        //Logo
        ViewBag.Logo = Server.MapPath("~") + @"Content\Images\Logo.png";
        return View("ShowForm");
    }
    

    And you don't have to change the code in your view.

    public ActionResult ShowForm()
            {
                ViewBag.Title = Resources.ApplicationTitle;
                ViewBag.LabelStatus = Resources.Status;
                //Logo
               byte[] imgbytes =  File.ReadAllBytes(@"C:\Images\Logo.png");
               return File(imgbytes , "image/png");
            }
    
    <div id="drawForm">
    <img src="controllerName/ShowForm" alt="Logo" />    
    </div>
