Right, if you just want a logo, in the middle of a page, here is the HTML:

Code:
<html>
<head>
    <title>My Page Title</title>
</head>
<body>
<table width="100%" height="100%">
    <tr>
        <td>
            <table>
                <tr>
                    <td>
                        <img src="myimagefile.jpg">
                    </td>
                </tr>
            </table>
        </td>
    </tr>
</table>
</body>
</html>
Copy & paste that into Notepad, replace the title text and the image filename as appopriate.
Save as "index.html" and then use as you wish.

HTML is the most piece of piss thing you will ever learn, trust me.
