title: Codeigniter error logs show a 404 non-existing images directory...need to worry?
body: <p>I've recently started logging my errors through codeIgniter. Since doing so, I have noticed a lot of 404 errors for directories that don't exist. For example:</p>
  
  <p>ERROR - 2010-05-15 21:06:26 --> 404 Page Not Found --> someController/images</p>
  
  <p>Where someController is, obviously, a controller. The problem is, there are no functions within that controller called images, nor are there any links to a directory by that name. Could this be that someone is trying to hack my site? If so, do I need to worry? If not, why is this happening? Thanks, and forgive the newby-ness. </p>
