Trouble With Conditional Logic in PHP

Did you tried dumping the value of $carousel_image
For image field to return Array, return_type must be set to array

https://www.advancedcustomfields.com/resources/register-fields-via-php/#field-type%20settings

/* (string) Specify the type of value returned by get_field(). Defaults to 'array'.
  Choices of 'array' (Image Array), 'url' (Image URL) or 'id' (Image ID) */
  'return_format' => 'array',

Also what’s the use of save_format in your code . I can’t find it in the documentation.
