[Plugin: Dynamic Links] MULTISITE relative links

Here is the code again:

function dlink_content_set_uploadbase ($content) {

	$options = get_option('dlink_settings');
	$blog_base = '';
	global $blog_id;
	$current_blog_details = get_blog_details( array( 'blog_id' => $blog_id ) );
	if( !empty($current_blog_details->blogname) ) {
		$blog_base = '/'.$current_blog_details->blogname;
	}
	if ($options['relative']) {
		$uploads = wp_upload_dir();
		$siteurl = site_url();
		if (substr($uploads['baseurl'],0,strlen($siteurl))==$siteurl)
			$path=substr($uploads['baseurl'],strlen($siteurl));
		else
			$path=$uploads['baseurl'];
		$content = str_replace('{uploads}', $blog_base.$path, $content);
	} else {
		$uploads = wp_upload_dir();
		$content = str_replace('{uploads}', $uploads['baseurl'], $content);
	}
	return $content;
}
