default image

Sorry but this might be issue for imagefield?

I didn't disable lightbox but I tried other options for image in my view (default, thumbnail...) without using lightbox and it doesn't work.
When viewing full node it works with lightbox, so i suppose it's not lightbox. Btw. I had to change some code to avoid broken link image when using default image, if you want to see this, it might be usefull for you: http://drupal.org/node/180592#comment-650042 and http://drupal.org/node/198311. Thank's for your answer.
Cheers,

It doesn't. I think that you made some typos in your patch. It should be:
return theme('imagefield_image_imagecache_lightbox2', $namespace, $field, $item);
not
return theme('imagefield_image_imagecache_lightbox2', $namespace, $field, $filepath, $item, $item['alt'], $item['title']);
there is not point to pass $filepath value to your theme because $filepath variable is not set in theme declaration.
function theme_imagefield_image_imagecache_lightbox2($namespace, $field, $item, $attributes = NULL).
With excluded (commented) $item = array_merge($item, $file); there is no "Text for Node Link" on the bottom of the image. On live site i'm using "v 1.16.2.17.2.17" but i tried newer versions on my localhost and there is no differencies except some minor issues i didn't like so i choosed older version. anyway this is what i've done:

function lightbox2_field_formatter($field, $item, $formatter) {
  if (module_exists('imagefield') && module_exists('imagecache')) {
  	if (isset($item['filepath'])) {
 	$filepath = &$item['filepath']; 
    } else if (!empty($item['fid'])) {
      $file = _imagefield_file_load($item['fid']);
      $filepath = &$file['filepath'];
    } else { 
      return '';
    }
    if (lightbox2_exclude_these_paths() != 1) {
      lightbox2_add_files();
    }
    $item = array_merge($item, $file);
    if (strpos($formatter, 'lightbox2][') !== false) {
      list($null, $namespace) = explode('][', $formatter, 2);
      $rules = _imagecache_get_presets();
      if (in_array($namespace, (array) $rules)) {
  
        return theme('imagefield_image_imagecache_lightbox2', $namespace, $field, $item, $filepath); 
      }
    }
  }
}

function theme_imagefield_image_imagecache_lightbox2($namespace, $field, $item, $filepath, $attributes = NULL) {
  $imagecache_path = file_create_url(file_directory_path() .'/imagecache/'. $namespace .'/'. $filepath); 
  $rel = 'lightbox';
  if (variable_get('lightbox2_image_group', TRUE)) {
    $rel = 'lightbox[cck_image_nodes]';
  }
  
  $node_link = '';
  if (!empty($item['nid'])) {
    $node_link = '<br /><br />'. l(t(variable_get('lightbox2_node_link_text', 'View Image Details')), 'node/'. $item['nid']);
  }
  
  $link_attributes = array(
    'rel' => $rel,
    'title' => $item['alt'] . $node_link);

 $image = theme('imagecache', $namespace, $filepath, $item['alt'], $item['title'], $attributes); 
 $output = l($image, file_create_url($filepath), $link_attributes, NULL, NULL, FALSE, TRUE); // ja dodao 
  return $output;
}
 

There is no differencies even if i don't change theme function but i did it because i think it will be important once when this issue with imagefield will be solved. I installed thickbox to check how it works and everything is same. For further explanation please check isuue that i've posted on imagefield: http://drupal.org/node/199647.
I'll sent you address and login for site to check page source. Thank you for your patience.

There is no "Text for Node Link (view image details)" on the bottom of the image without $item = array_merge($item, $file);
I put
$item = array_merge($item, (array)$file);
and it works without throwing error "array_merge() [function.array-merge]: Argument #2 is not an array in..." when using lightbox2 for images in full node preview.

I already have that so i can tell you that it works...for now :) I've sent you address and login on my site via your contact so if you want to see ... but i'm sure it's imagefield issue. I can't get that default image on my view, as I said when viewing full node it works with imagecache and lightbox now.
