Final answer:
To navigate to the correct image when a merchant selects a slideshow section in the theme editor, listen for the shopify:section:select event.
Step-by-step explanation:
If you are building a slideshow section and want the theme editor to navigate to the correct image when the merchant selects it, you should listen for the shopify:section:select event. This event is triggered when a merchant selects a section within the theme editor. Listening to this event will allow you to respond appropriately by navigating to or highlighting the selected image in the slideshow.
