WordPress How to make image/logo in the header clickable

Applies for WordPress TwentyTen Theme

search for this

<img src=“<?php header_image(); ?>“ width=“<?php echo esc_attr( $header_image_width ); ?>“ height=“<?php echo esc_attr( $header_image_height ); ?>“ alt=““ />

turn into this:

 

<a href=“/“>
<img src=“<?php header_image(); ?>“ width=“<?php echo esc_attr( $header_image_width ); ?>“ height=“<?php echo esc_attr( $header_image_height ); ?>“ alt=““ />
</a>

So much for the wrong Blabla…
