The style sheet and the images you are using is in the classic folder

<link rel="stylesheet" type="text/css" href="includes/templates/classic/css/stylesheet.css" />

includes/templates/classic/images/logo.gif


So you are using the classic template.

I would advise you add a new template in the templates folder and give it a unique name (like record) and copy the images and stylesheet folder and the template_info.php into it. Edit the template_info.php to reflect the new name. Then you make a folder called common inside your new template folder then go to the template_default folder and copy the tpl_header.php and paste it inside your new templates common folder.

Log into admin and Tools then Template Selection and select your new template.

Each time you need to edit a file and it is not in your new template you need to copy it out of the template default and paste it into your new custom folder
