    Cannot get the image path or any other value

    Hi, I am trying to get the value(s) of an image in a partial view. I am trying to get the image url. I can get the other page elements like title, description but not the image. It is created using imageCropper.

    Here is the error: System.ArgumentException: 'The value "Umbraco.Web.PublishedModels.ImageBanner" is not of type "Umbraco.Web.PublishedModels.Image" and cannot be used in this generic collection. Parameter name: value'

    here is my code for looping through the banners on our site:

    ISiteService SiteService = Current.Factory.GetInstance<ISiteService>();
    IPublishedContent banner_list = SiteService.GetContentUsingAlias("bannerSettings");
    if (banner_list.ContentType.Alias == "bannerSettings")
    {
    
    foreach (var item in banner_list.Children())
    {
        var a = item.GetProperty("bannerTitle").Value();
    
        var b = item.GetProperty("bannerDescription").Value();
    
        var c = item.GetProperty("bannerImage").Value();
    }
    

    We are adapting code from our Umbraco 7 website. This is what works in Umbraco 7, but not in Umbraco 8:

    var banner_list = new DynamicNode(-1).DescendantsOrSelf("bannerSettings").First();
    var bobj = new Dictionary<string, Dictionary<string, string>>();
    if (banner_list.NodeTypeAlias == "bannerSettings")
    {
       foreach (var item in banner_list.Children.Select((val, i) => new { i, val }))
       {
              var banners = new Dictionary<string, string>();
              foreach (var ite in item.val.PropertiesAsList)
              {
                 banners.Add(ite.Alias, (ite.Value.Contains("umb://") ? Umbraco.TypedMedia(ite.Value).Url : ite.Value));
               }
              bobj.Add(item.val.Name.ToLower().Replace(" ", ""), banners);
         }
      }
    }
    

    Any help would be terrific here. Thank you.

    Pete

    Hi all, Just solved the above question, in a way. I changed the banner image to a normal image (out of the box, so to say) in the media section. I had created my own folder type and media picker.

    Now, using the following I can get the image properties etc.

    var c = item.GetProperty("bannerImage").Value<IPublishedContent>();
    
      var d = c.Url;
    

    I think it would be handy if someone came up with a solution for the original error when I created a new ImageCropper and media Picker.

    Thank you
