how to show a default image

Thanks a lot

I actually end up with this code

<%
file = new File(application.getRealPath("attachments/images/" + chapter_ID + "SIMAGE.jpg"));
if(file.exists()){
              %>
                    <tr>
                        <td><img src="attachments/images/<%=chapter_ID%>SIMAGE.jpg" width="140" height="140"></td>
                    </tr>
              <%
                  }else{
              %>
                    <tr>
                        <td><img src="attachments/images/DefaultSIMAGE.jpg" width="140" height="140"></td>
                    </tr>
              <%
                }
              %>
            

If you don't mind I just wanted to know what does this code do

else{ response.sendRedirect(request.getContextPath() + "/default.jsp"); return;}

>if it doesn't show a default page  
I thought you wanted to go to another page. The code would have redirected the browser.

ok, thanks
