    In my field group, the return value is Image URL. Should it be something else?

  • The moment I changed $image['url'] to just $image the url outputted and no more error, but for the alt it was still an issue.

  • Ah, changed the return value to Image Array and that worked. Whoops.

  • I was about to ask what you were returning reading the OP. Glad you got it worked out.
