I'm creating a small repository for products. I'm giving the user the ability to select a "Coming Soon" product. I have set up a specific "ComingSoon" doc type and there is an image in the media library that I want to display every time this doc type is used. How can I do that? I can display the image of "actual products" without any problems.

Here is my code so far

 @{var categories = Model.Children;
    foreach(var subpage in categories)
    {
                    @if (subpage.NodeTypeAlias == "ComingSoon")
                    {
                        var defaultImage = Library.MediaById(1175);
                        <img src="@Library.MediaById(1175)" alt="@defaultImage.altText" />
                    }
                    else
                    {
                        <a href="@subpage.Url">
                        <img src="@subpage.Media("mainImage", "umbracoFile")" alt="@subpage.Media("mainImage", "altText")" />
                        </a>
                    }
    }
    }

Thanks
