This code somehow just stopped working and displaying an error message when using Replace to display a cropped image.

Any suggestion ?

@{
  var newsItems = Model.NodeById(2148);
  var sortedItems = newsItems.Children.OrderBy("createDate descending");
  var itemsPerPage = 5;
  foreach(var page in sortedItems.Where("visible").Take(itemsPerPage))
  {   
     <li><a href="@page.Url">@page.Name </a>&nbsp;</li>
    <li><a href="@page.Url">@Library.Truncate(@Library.StripHtml(page.newsDesc), 50)</a></li>
    <li> <img src="@page.Media("newThumb","umbracoFile").Replace(".jpg","_thumb.jpg")" height="150" width="224"/></li>
      }
  }
