Logo Mouse Over Alt text

Where does one change the alt text in the logo/header?

Mine says "Powered by Zen Cart: The art of ecommerce"

In includes/languages/english/YOUR_TEMPLATE/header.php look for the line I highlighted in red and change as desired.

// added defines for header alt and text
define('HEADER_ALT_TEXT', 'Powered by Zen Cart :: The Art of E-Commerce [home link]');define('HEADER_SALES_TEXT', '<h1>Sales Message Goes Here</h1>');
define('HEADER_LOGO_WIDTH', '200px');
define('HEADER_LOGO_HEIGHT', '70px');
define('HEADER_LOGO_IMAGE', 'logo.gif');

That line has been changed, but to no avail.

Where else should I look?

As far as I know, that's the only place. I did a search in the admin of one of my sites using the Developer's Toolkit and that's the only place that phrase shows up (outside of one admin file).

It is very mysterious :) I've checked and triple checked every file.

On "View Source", it comes up as the logo alt text. Can't find the "define" line anywhere.

Cue Twilight Zone music.
