I've created an image 'field_term_preview' field on the taxonomy vocabulary and trying to get this URL in my custom module:

$terms =\Drupal::entityTypeManager()->getStorage('taxonomy_term')->loadTree($vid, 0, null, true); foreach ($terms as $term) { if ($term->getName = 'Term with preview') { foreach ($term->getFields(true) as $field) { if ($field->getName() == 'field_term_preview') { var_dump($field->getValue()); } } } }

This code shows only target_id, alt, height, etc. enter image description here

How to get the URL to the preview image?

In Drupal images are File entities, the target_id is the File ID. So...

$fid = $field->getValue()[0]['target_id']; // File ID, // Note the [0] in the array. We assume there is always going to be 1 image here. // If your field allows more than 1 image, you will need to loop through each $field->getValue() $file = \Drupal\file\Entity\File::load($fid); // load File entity object $file_url = $file->url(); // get the URL.
