All I know about lightbox is that you provide custom classes to your images, then you set those custom classes in the Lightbox settings and it should work. If it isn't working then you need help from someone who knows more about it, probably in the Lightbox forum.

Go to: http://www.yoursite.com/admin/settings/lightbox2/automatic -- enter in any name for the automatic preset then hit save.

Then go to http://www.yoursite.com/admin/settings/fbsmp/plugins/photo

Enter in that same name (nothing else) in Additional Classes and hit save.

Same problem with colorbox. Overlay is loaded, but stills in "loading". This only happens with Facebook-style Micropublisher

@AntiNSA, for you have add class to link not to image.

that's adding to image:

Then go to http://www.yoursite.com/admin/settings/fbsmp/plugins/photo

Enter in that same name (nothing else) in Additional Classes and hit save.

This is still an issue for D7 and Colorbox because Colorbox requires the class "colorbox" to be set on the link, not the image.

To fix without hacking the module, set the the ImageCache preset to "... linked to image", then add the following to your template.php:

function yourtheme_fbsmp_photo_attachment_imagecache($variables) {
  $presetname = $variables['preset'];
  $style = $variables['style'];
  $attachment = $variables['attachment'];
  $alt = $variables['alt'];
  $title = $variables['title'];
  $attributes = $variables['attributes'];
  
  $attachment_data = $attachment->data;
  $file = (array) _fbsmp_file_load($attachment_data['fid']);
  if (!is_file(drupal_realpath($file['uri']))) {
    return '<!-- File not found: ' . check_plain($file['filename']) . ' -->';
  }

  switch ($style) {
    case 'default':
      return theme('image_style', array('style_name' => $presetname, 'path' => $file['uri'], 'alt' => $alt, 'title' => $title, 'attributes' => $attributes));
    case 'imagelink':
      $thumbnail = theme('image_style', array('style_name' => $presetname, 'path' => $file['uri'], 'alt' => $alt, 'title' => $title, 'attributes' => $attributes));
      $url =  file_create_url($file['uri']);
      return l($thumbnail, $url, array('html' => TRUE, 'attributes' => array('class' => 'colorbox')));
    case 'path':
      return image_style_path($presetname, $file['uri']);
    case 'url':
      return image_style_url($presetname, $file['uri']);
  }
}

The real fix would be to add the ability to add a custom class to either image OR the link.

Cheers,
Andrey.
