Looking for guesses on where my menu icons are stored

I have our site designer set up the wordpress blog and I promised myself I would not tinker with the main stuff….but I have. I accidentally deleted the menu icons that go across the top of the page (they are the categories of our store). Can anyone guess where these would be stored in cpanel? I was able to delete them from the wordpress admin, but I am guessing that I have to go in cpanel and tinker to get them back up. Any ideas are appreciated!
