  | 	public void setPicturedata(InputStream data) ;
  | 	public String getContentType() ;
  | 	public void setContentType(String contentType);
  | 	public String getFileName();
  | 	public void setFileName(String fileName);
  | 	public String getTitle() ;
  | 	public void setTitle(String title);
  | }
  |

  | 		return "";
