    Hi,
    I’m trying to follow the steps here to display several thumbnails in my theme using customs fields.

    I have it working now so it will display several custom fields with the name “image”. See my code here:

    <?php

$mykey_values = get_post_custom_values('image');
foreach ( $mykey_values as $key => $value ) {
echo '<img src="'.$value.'">';
}
?>

    My problem is if there is no custom field with the “image” name then I get a PHP error. How do I make this an if statement? Obviously my PHP skills are bad. Thanks!

    try this

    <?php
$mykey_values = get_post_custom_values('image');
if ($mykey_values) {
  foreach ( $mykey_values as $key => $value ) {
    echo '<img src="'.$value.'">';
  }
}
?>
