We at WePlugins, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function weplugins_execute_on_admin_print_styles-media-upload-popup_event and we registered it using add_action. The first parameter admin_print_styles-media-upload-popup is the name of the hook, The second parameter weplugins_execute_on_admin_print_styles-media-upload-popup_event is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times, and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_action to remove admin_print_styles-media-upload-popup action.
