TimThumb doesn’t work with WordPress Multisite

I've created a WordPress Multisite usin the sub-folder method.

  • site_name.com
  • site_name.com/es

The theme has the TimThumb script for image resizing.

Then I found a problem. My second site (es) was not loading any images.

  • site_name.com/wp-content/uploads/2011/09/05/image.jpg
  • site_name.com/wp-content/es/files/2011/09/05/image.jpg

WordPress builds a cool link for the "es" site but it doesn't work if you use it with TimThumb.

If you open your FTP client you would find the file under:


That's the path you will have to use with TimThumb.

Something like this:

function get_image_path ($post_id = null) {
	if ($post_id == null) {
		global $post;
		$post_id = $post->ID;
	$theImageSrc = get_post_meta($post_id, 'Image', true);
	global $blog_id;
	if (isset($blog_id) && $blog_id > 0) {
		$imageParts = explode('/files/', $theImageSrc);
		if (isset($imageParts[1])) {
			$theImageSrc = '/blogs.dir/' . $blog_id . '/files/' . $imageParts[1];
	return $theImageSrc;
