Display data from custom field from attached image in post

    Hi all,
    I found a way to add custom fields to an attached photo but I don’t know how to display the input from those fields. I have a custom field called ‘photocredits’ and want to display the data from that custom field in the image, just like a caption.

    I’m using this to display the image:

    <?php $thumb_id = get_post_thumbnail_id($post->id); $args = array(	'post_type' => 'attachment','post_status' => null,'post_parent' => $post->ID,'include'  => $thumb_id);
		$thumb_images = get_posts($args);
		foreach ($thumb_images as $thumb_image) {
		if($thumb_image->[customfield]) echo '<h2><span>','Image: ' . $thumb_image->[customfield] . '</h2></span>';
		}
		?>

    and [customfield] is where data from the custom field is to be displayed.

    Any help would be greatly appreciated.

    Thanks,
    Gregory S.

    I’m not sure about using custom fields, but when you upload an image you have the option to add a caption.
    In the past I’ve used this code:

    <?php if(has_post_thumbnail()) {
	the_post_thumbnail();
	echo '<span class="caption">'. get_post(get_post_thumbnail_id())->post_excerpt .'</span>';
	}

    The post_excerpt is what generates the content in the caption field.

    I appreciate the help but it didn’t solve the problem. I’m using Bill Erickson guide for adding custom fields for image attachments

    http://www.billerickson.net/wordpress-add-custom-fields-media-gallery/

    It’s setup exactly as it is in the guide, I’m just stuck on how to get the custom field to be displayed on my site.

    I wish you would have sent that link earlier. It makes more sense now.

    I see that Bill has provided an answer on his post. Hope that helps.

    OK, I finally got it working but I need someone to verify that the code I have is correct. What I want it to do is check the custom field [photo_credits] for data, if it does then add the word ‘Image:’ before the text. I’ve done this before with the caption but I’m having problems trying to get it to work with the custom fields.

    Here’s what I’ve done so far:

    <?php
		$attachments = get_children( array('post_parent' => get_the_ID(), 'post_type' => 'attachment', 'post_mime_type' =>'image') );
		foreach ( $attachments as $attachment_id => $attachment ) {
		if get_post_meta($attachment_id, 'photo_credits', true); echo '<h2><span>','Image: ' . echo get_post_meta($attachment_id, 'photo_credits', true); . '</h2></span>';
		} ?>

    If it helps, this code is based on the previous question – http://wordpress.org/support/topic/add-additional-text-to-photo-caption?replies=3

    Thanks for all the help so far,
    Gregory S.
