	{
		public static string ForFileName (string fileName)
		{
			//Any old images with a full file path stored should have the front part removed
			if (fileName.Contains ("/"))
			{
				fileName = fileName.Substring (fileName.LastIndexOf ("/") + 1);
			}
			var docsDir = Environment.GetFolderPath (Environment.SpecialFolder.Personal);
