Get thumbnail from page? (Concrete 5.7.4.2) - concrete5

Question

As posted here https://www.concrete5.org/index.php?cID=751287 I want to get a thumbnail from a page using the 'old' way.
Before I could use the code below which included an image helper.
<div class="image-link">
<a <?php if ($target != '') { ?> target="<?php echo $target ?>" <?php } ?> href="<?php echo $url ?>">
<?php
$ts = $page->getBlocks('Thumbnail Image');
if (is_object($ts[0])) {
$tsb = $ts[0]->getInstance();
$thumb = $tsb->getFileObject();
if ($thumb) {
$ih->outputThumbnail($thumb, 170, 80, $title);
}
}
?>
</a>
</div>
From this section of the subpage:
<div id="thumbnail">
<?php
if ($c->isEditMode()) {
print '<br><br>';
$a = new Area('Thumbnail Image');
$a->display($c);
}
?>
</div>
However now this has all changed and the new system uses page attributes for thumbnails. As the site is already setup the 'old' way I want to be able to retrieve the thumbnail the same way again.
Any help would be much appreciated.

Answer 1

I have "thumbnail" page attribute set via the composer, and this is how I retrieve it in the page template:
<?php
$thumbnail = $c->getAttribute('thumbnail');
if($thumbnail) {
$img = Core::make('html/image', array($thumbnail));
$tag = $img->getTag();
print $tag;
}
?>

Answer 2

I dug out my experimentation hat and fixed it.
<div class="image-link">
<a <?php if ($target != '') { ?> target="<?php echo $target ?>" <?php } ?> href="<?php echo $url ?>">
<?php
foreach ($blocks as $block) {
if ($block->getBlockTypeHandle() == "image" && $block->getAreaHandle() == "Thumbnail Image") {
if (is_object($block)) {
$tsb = $block->getInstance();
$thumb = $tsb->getFileObject();
if ($thumb) {
$ih->outputThumbnail($thumb, 170, 80);
}
}
}
}
?>
</a>
</div>
