Added Lightbox2 Support

Here is how I make weblinks open up in Lightbox2 (http://drupal.org/node/144469).

1. Of course, install and enable Lightbox2 module.

2. Add 2 identical code snippets to weblinks.module. The first instance is around line 403. The second instance is around line 1017. Just after this:

    if (variable_get('weblinks_nofollow', FALSE)) {
      $options['attributes']['rel'] = 'nofollow';
    }

add this

// Add lightbox2 lightframe display option
    if (variable_get('weblinks_lightframe', FALSE)) {
      $options['attributes']['rel'] = 'lightframe';
    }

3. In weblinks.admin.inc, just after this:

  // Add "rel=nofollow."
  $form['page']['weblinks_nofollow'] = array(
    '#type' => 'radios',
    '#options' => $yesno,
    '#prefix' => '<div class="weblinks-radios">',
    '#suffix' => '</div>',
    '#title' => t('Spam link deterrent'),
    '#default_value' => (int) variable_get('weblinks_nofollow', FALSE),
    '#description' => t('If enabled, Drupal will add rel="nofollow" to all links, as a measure to reduce the effectiveness of spam links. Note: this will also prevent valid links from being followed by search engines, therefore it is likely most effective when enabled for anonymous users.'),
    );

add this

// Add lightbox2 lightframe display option
  // Add "rel=lightframe."
  $form['page']['weblinks_lightframe'] = array(
    '#type' => 'radios',
    '#options' => $yesno,
    '#prefix' => '<div class="weblinks-radios">',
    '#suffix' => '</div>',
    '#title' => t('Lightbox2 popup display'),
    '#default_value' => (int) variable_get('weblinks_lightframe', FALSE),
    '#description' => t('If enabled, Drupal will add rel="lightframe" to all links to show the site in a Lightbox2 frame popup.'),
    );

4. I also changed the width of the lightbox to 900px in /admin/settings/lightbox2/html_content
