            public string GetUrl()
            {
                 var currentItem = Sitecore.Context.Item;
                 var imageUrl = string.Empty;

                 Sitecore.Data.Fields.ImageField imageField = currentItem.Fields["Image"];
                 if (imageField?.MediaItem != null)
                 {
                     var image = new MediaItem(imageField.MediaItem);
                     imageUrl = StringUtil.EnsurePrefix('/', MediaManager.GetMediaUrl(image));
                 }
