 * Hey
 * Im trying to do a plugin that will keep the users header after theme change. 
   So far i come up with this.
 *     ```
       <?php 
   
       add_action('pre_update_option_theme_mods_' . get_option( 'stylesheet' ), save_header_image_as_option);
       add_action('switch_theme', 'keep_header'); 
   
       error_log("stylesheet " . get_option( 'stylesheet' ),0);
       error_log("prevous header " . get_option( 'previous_header_image_saved' ),0);
   
       function save_header_image_as_option()
       {
       	$details_before = get_theme_mods($blog_id);
       	update_option("previous_header_image_saved", get_theme_mod('header_image'));
       	error_log("before theme change" . json_encode($details_before), 0);
       	return $details_before;
       }
   
       function keep_header()
       {
       	$details_after = get_theme_mods($blog_id);
       	set_theme_mod('header_image', get_option("previous_header_image_saved"));
       	error_log("after theme change" . json_encode($details_after), 0);
       	return $details_after;
       }
   
       ?>
       ```
   
 * Sadly it does not work, because the trigger is also triggede when trying to CHANGE
   the header. Any suggestion on how to accomplish to keep header when changing 
   themes ?

 * Ended up with this:

       <?php
       /**
        * @package Preserve_Header_Image
        * @version 1.0
        */
       /*
       Plugin Name: Preserve_Header_Image

       Description: Preserve header image between stylesheet (theme) switchings.

       add_action('pre_update_option_stylesheet', 'phi_pre_update_option_stylesheet');
       add_action('switch_theme', 'phi_switch_theme');
   
       function phi_pre_update_option_stylesheet($stylesheet)
       {
               update_option('previous_header_image_saved', get_theme_mod('header_image'));
   
               return $stylesheet;
       }
   
       function phi_switch_theme()
       {
               if (get_option('previous_header_image_saved')) {
                       set_theme_mod('header_image', get_option('previous_header_image_saved'));
                       delete_option('previous_header_image_saved');
               }
       }
       ?>
       ```
