I'm struggling to make template suggestions like IMAGE--BLOCK-TYPE or IMAGE--FIELD-TYPE. I have three different block types(image1, image2, image3) with one image field(field_image_1, field_image_2 and field_image_3). And I don't know how to get suggestion like

image--block_image1.html.twig
image--block_image2.html.twig
image--block_image3.html.twig

or

image--field_image_1.html.twig
image--field_image_2.html.twig
image--field_image_3.html.twig

Is there any way to pass variable between the two hooks below?

  function full_nature_theme_suggestions_block_alter(array &$suggestions, array $variables) {

    global $block_id;

    $block_id = $variables['elements']['#id'];

  }

and

  function full_nature_theme_suggestions_image_alter(array &$suggestions, array $variables) {

    $suggestions[] = 'image__'.$block_id;

  }

Please help!

Solution is here

It is alternative solution but it works with this module

This is right solution but it works only with this module https://www.drupal.org/project/image_class

/**
 * Implements hook_theme_suggestions_HOOK_alter().
 */

function full_nature_theme_suggestions_image_alter(array &$suggestions, array $variables) {
  $image = $variables['attributes']['class'][0];
  $suggestions[] = 'image__'.$image;
}
