This code snippet will add a collapsible fieldset containing a preview of the node you are attempting to delete.

<?php
function MYMODULE_form_alter($form_id, &$form) {
  if ($form_id == 'node_delete_confirm') {
    $form['nodePreviewFieldset'] = array(
      '#type' => 'fieldset',
      '#title' => 'Preview',
      '#weight' => 10,
      '#collapsed' => TRUE,
      '#collapsible' => TRUE,
    );
   
    $form['nodePreviewFieldset']['nodePreview'] = array(
      '#value' => node_view(node_load(arg(1)), TRUE, FALSE, FALSE)
    );
  }
}
?>

I created an image node type using the CCK module imagefield. Here is how you can show a preview of the image being deleted on the confirmation page...

<?php
function MYMODULE_form_alter($form_id, &$form) {
  // ...code...
  if ($form_id == 'node_delete_confirm') {
    _MYMODULE_form_alter_node_delete_confirm_user_image($form);
  }
  // ...code...
}

function _MYMODULE_form_alter_node_delete_confirm_user_image(&$form) {
   
  // NOTE: This function assumes the file system path is set to private, which is needs to be for this application
   
  $node = node_load(arg(1));
  if ($node->type != 'user_image') return;
   
  $maxDimension = 300;
  $imagePath = file_create_path($node->field_user_image[0]['filepath']);

  // NOTE: this is a simple function I created that accepts 2 parameters (an image page and a maximum dimension) and it returns resized image dimensions
  $imageDimensions = _MYMODULE_images_resize($imagePath, $maxDimension);
   
  // create image html
  $img = "<img style='margin: 25px;' width='{$imageDimensions['width']}' height='{$imageDimensions['height']}' src='/system/files/" . $node->field_user_image[0]['filename'] . "' />";
   
  // add image to form
  $form['image_preview'] = array(
    '#value'    => $img,
    '#weight'    => 10,
  );
   
}
?>
