Thank you Etienne. You got me on the right track. Here is the full code that should go in functions.php:

// Deal with images uploaded from the front-end while allowing ACF to do it’s thing
function my_acf_pre_save_post($post_id) {

if ( !function_exists(‘wp_handle_upload’) ) {
require_once(ABSPATH . ‘wp-admin/includes/file.php’);
}

// Move file to media library
$movefile = wp_handle_upload( $_FILES[‘my_image_upload’], array(‘test_form’ => false) );

// If move was successful, insert WordPress attachment
if ( $movefile && !isset($movefile[‘error’]) ) {
$wp_upload_dir = wp_upload_dir();
$attachment = array(
‘guid’ => $wp_upload_dir[‘url’] . ‘/’ . basename($movefile[‘file’]),
‘post_mime_type’ => $movefile[‘type’],
‘post_title’ => preg_replace( ‘/\.[^.]+$/’, ”, basename($movefile[‘file’]) ),
‘post_content’ => ”,
‘post_status’ => ‘inherit’
);
$attach_id = wp_insert_attachment($attachment, $movefile[‘file’]);

// Assign the file as the featured image
set_post_thumbnail($post_id, $attach_id);
update_field(‘my_image_upload’, $attach_id, $post_id);

}

return $post_id;

}

add_filter(‘acf/pre_save_post’ , ‘my_acf_pre_save_post’);
