order confirmation email

I wish to get rid of the Zen Cart header for the confirmation email. Anyone know where to find that file?

To remove the logo from Order Confirmation email:

@ZC1.5.4: /email/email_template_checkout.html
arround line #42: comment out

Code:

---

<!-- Header Section -->
  <!-- <div class="header">
  <img src="email/header.jpg" alt="logo" />
  </div> -->
