Top Banner Slogan and how to change it

I have one last issue that I would be greatful if someone could help me on. The default template has a banner upper left that says...YOUR STORE and under it say's "your company slogan"  What PHP or CSS file do I get into to change that?  I saw no option in the store set up to change that.  Thanks.

Hi Joey,

In the file "catalog/template/default/css/default.css", you'll find a section starting with the following code:- The referenced image is located in the "catalog/template/default/image" directory.

That image is stricly the gradient BG that is aligned at the top via the CSS rule.  The actual banner text is something different.  I already changed the BG image but the actual text is still there upper left corner which leads me to believe that it is elsewhere to be edited.  Get me?

I found the CSS that I needed to change. The following :
#header .a {
background: url('../image/logo.png') no-repeat;
behavior: url('catalog/javascript/png/iepngfix.htc');
width: 157px;
height: 32px;
float: left;
position: absolute;
top: 22px;
left: 10px;
}

default.css withen the template.  The logo.png is the image. 
THANKS AGAIN
