Question

1C-Bitrix

I have a background div

<div class="promo__wrap" style="background-image: url(<?=SITE_TEMPLATE_PATH?>/images/registration/registration-page-fon1.jpg);">

The task is that the picture can be changed in edit mode. How to implement this functionality. Write a component? Maybe there is an easier way?
Thought to do it via news.detail . Rational?
