Codeigniter error logs show 404 non-existent image directories ... need to worry?

Question

I recently started logging my errors using codeIgniter. After that, I noticed a lot of 404 errors for directories that do not exist. For instance:

ERROR - 2010-05-15 21:06:26 → 404 Page not found → someController / images

Where someController is obviously a controller. The problem is that there are no functions called images inside this controller, and there are no links to a directory with this name. Maybe someone is trying to hack my site? If so, do I need to worry? If not, why is this happening? Thanks, and sorry newby-ness.
