Logo doesn't appear on each page.

I’m new to this forum so forgive me if I am not clear.

I am creating a website, https://www.wpbasketball.com.

The logo I created appears on the home page. However, it doesn’t appear on any of the other pages.

Any suggestions on what I’ve done wrong?

Here is my code for the logo (in my header.php file). I am using a child theme (TwentyTwelve):

<div id=”logo”>
/”><img src=”./wp-admin/images/logo.png” height=”125″ width=”125″ alt=”‘WP Basketball” title=”logo”/>

Thanks.
