Lightbox compatibility : replace href tags

Other solution could be to give us function with2 parameters : URL and type (img, js, css).
Someting like parallel_replace_url($url, $type)

Then we use it to replace our URLs before to write them in our templates when we know its an image.

This solution isn't as nice and global. But it's a simple one.

I think this patch will not perfectly work.
It replace all URL from /files directory with Parallel IMG alias even if that's not an image.

In my theme file : template.php
I created this function :

function cdn_url($_url) {
  if (variable_get('parallel_enabled', TRUE) && variable_get('parallel_domain_img', '') != '') {
    $base_url = variable_get('parallel_domain_img', $base_url);
    
    return $base_url.'/'.$_url;
  }
  else {
    return url($_url);
  }
}

And I use it this way :

$mypicture_lightbox = cdn_url(imagecache_create_path('lightbox2', $mypicture['filepath']), array('absolute' => TRUE));

cdn_url($url) is used same way as url($url) : http://drupalcontrib.org/api/function/url/6

I use cdn_url($url) in my template when I construct Lightbox tag manually. It works.

But it doesn't resolves problem when Lightbox tag is constructed by Views for example.

EDIT:
Sorry Parallel module works for automatic Lightbox tags in Views with Lightbox rendering image.
So my problem was just for Lightbox tags generated manually in template.php.
In this case using cdn_url($url) solves my problem.

Similar problem with ColorBox module.
