Random image from Repeater issue

Hello.
I am building out a repeater that calls an image.
The image is to be random on each page reload.
As reference I started with this code snippet/example:
http://www.advancedcustomfields.com/resources/repeater/

Here is a screenshot of my Repeater:

Here is my code:

<?php
  $rows = get_field('jdh_homepage_images' ); // get all the rows
  $rand_row = $rows[ array_rand( $rows ) ]; // get the first row
  $rand_row_image = $rand_row['jdh_homepage_image']; // get the sub field value
  $image = wp_get_attachment_image_src( $rand_row_image, 'full' );
?>

This line did not work:
<?php echo $image[0]; ?>

But this line did:
<?php echo $rand_row_image; ?>

Thank you for any help with this issue.

What are you returning from the image field? Array, URL or ID

If you’re returning the URL then you don’t need to do the last line wp_get_attachment_image_src. You only need to do that if you’re returning the ID.

@hube2 So I can remove $image = wp_get_attachment_image_src( $rand_row_image, 'full' ); and the should still work?

Yes, if you’re returning the url then $rand_row_image; already has what you want.
