I'm creating a setting to set a logo. It works but there is a problem.  

I only need one image to be set so the gallery item should be disabled / hidden. Of course this should only effect this page, of even better this setting.

```
<?php
// above this I do a simple settings api
?>
<input id="set_logo" type="text" size="100" name="set_logo" value="<?php echo esc_attr( $value ); ?>" />
<?php
do_action( 'media_buttons', 'set_logo' );

```

I've looked in multiple places in code but I can't find any clues how to do this.

**EDIT**  

I've solved it in a different way that is not related to this. The solution is now implemented in my first plugin: <http://wordpress.org/extend/plugins/default-featured-image/>  

*shameless plug.*
