image location

I have no clue where this image is being coming from. Is there a template of some sort where it is being relayed? I need to find where this is coming from so I can change the image and actually know where to look for future updates.

I am also knew to Drupal and our company got a new client to perform additions and updates to their website, so we are all learning. This has been our only issue, so far.
