    Get Multiple Images from Media Picker from another Model

    I have a Master template which has the header and footer for each page.

    Each page thereafter is rendered inside that Master template using @RenderBody().

    In the Hompage Model I have a media picker using multiple images.

    I can call the media picker on the homepage but not on any other page

    Works on hompega eusing the following

     @{   var typedMultiMediaPicker = Model.Content.GetPropertyValue<IEnumerable<IPublishedContent>>("asscoiates_logos_slider");
    
      foreach (var item in typedMultiMediaPicker)
       {
        var URL = item.GetPropertyValue<string>("imageURL");
        <div>
        <a href="@URL" target="_blank"><img src="@item.Url" alt="" /></a>
       </div>
         }
         }
    

    When displaying from a page that is not the homepage i get error

    System.NullReferenceException: Object reference not set to an instance of an object.

    Im thinking its because the properties are set on the homepage therefore works on home page.

    Otherwise : How do I do recursive with multiple images with media picker.

    Hi James

    Where media picker placed? Is it on the home page node?

    I think you have to call media picker in the home page like that:

    var homePage = Umbraco.AssignedContentItem.AncestorOrSelf(1);
    
    var typedMultiMediaPicker = homePage.GetPropertyValue<IEnumerable<IPublishedContent>>("asscoiates_logos_slider");

    Awesome Alex, that's the ticket.

    I had that same idea as well but using different code which was wrong, perfect - Thanks a lot :)
