Show all other attachment images on attachment template

$arrImages has all of the image attachment objects in an array, but the provided code only uses the first image. You need a foreach loop to process every attachment. wp_get_attachment_image() will return a complete <img> tag given an attachment ID from the current object in the loop.

get_permalink() in the proffered code will just link to the current page. If you want to link to other attachment pages use get_attachment_link().

Dzień dobry. I know Poland. Beautiful country. I spent some time there visiting some Polish friends. I don’t need anything wild, but thanks for the offer. I think you could have pulled this together on your own if you had really tried. Maybe it wouldn’t be perfect and you’d still need help, but you will more likely get help if you’re already making your own best effort. But since you asked nicely, here you are:

function bdw_get_images() {
 
    // Get images for this post
    $arrImages = get_children('post_type=attachment&post_mime_type=image&post_parent=' . get_the_ID() );
 
    // If images exist for this page
    if($arrImages) {
 		foreach ( $arrImages as $img ) {
 		
		    // Build the <img> string
		    $sImgString = '<a href="' . get_attachment_link( $img->ID ) . '" class="bdw-img-link">' .
		                        wp_get_attachment_image( $img->ID, 'thumbnail') .
		                    '</a>';
	 
		    // Print the image
		    echo $sImgString;
        } //end foreach
    } //end if
}

You can specify other image sizes besides “thumbnail” in wp_get_attachment_image(). The actual width displayed depends on your site’s CSS. You might need to add something like this to Additional CSS in the customizer:

a.bdw-img-link {
   width: 150px;
   float: left;
   margin: 20px;
}

Coordinate the width value with the image size used.

Hmmm… I think get_the_ID() is inappropriate, my bad. Please replace with this: $post->post_parent
Because we need the ID of the current attachment’s parent post. Attachments don’t have children themselves.

Also place global $post; as the first statement of the function.

Hey, “trial and error” is my favorite method too! 🙂

Thank you for the kind offer, but offering payment or any sort of compensation is not allowed in these forums. In any case, I’m not available for off-forum work. You can always ask questions in these forums. I or someone will try to answer, but don’t expect much in the way of custom coded solutions unless it’s fairly simple. It usually works better if you post a code snippet of your best effort and ask what’s wrong or needed to get it to work. I know you’re not a programmer, but it seems you have some modest coding skills.

You shouldn’t ever modify existing code. There’s normally some way through hooks or other means to modify behavior by adding your own code. All of your custom code can reside in a child theme or custom plugin. There you may modify or add as much as you like.
