I believe ‘galery-head’ field is an image or gallery field; that’s why
Array because the returned data is an array. Please take a look at this page to learn how to use an image field: https://www.advancedcustomfields.com/resources/image/, and this page to learn how to use a gallery field: https://www.advancedcustomfields.com/resources/gallery/.
You can also check how to show an image field in a repeater here (under the “Advanced Loop” section): https://www.advancedcustomfields.com/resources/repeater/.
I hope this helps 🙂
