need help with a custom function (1 post)

    I am trying to get timthumb working with wpmu. Having followed the directions on his site, I am able to successfully grab a 'thumb' custom field and have it show up in my post using the following code:

    function get_image_path ($post_id = null) {
    	if ($post_id == null) {
    		global $post;
    		$post_id = $post->ID;
    	}
    	$theImageSrc = get_post_meta($post_id, 'thumb', 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;
    }

    What I would like to do is have a function that will search the post for the first image, and then return that image url 'properly formatted for wpmu with the 'blogs.dir/#/files' within the url so that timthumb can function.

    Here is the function that I am using currently which works with non-mu sites, but does not work with wpmu.

    /*this function allows users to use the first image in their post as their thumbnail*/
    function catch_that_image() {
    	global $post, $posts;
    	$first_img = '';
    	ob_start();
    	ob_end_clean();
    	$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
    	$first_img = $matches [1] [0];
    
    	return $first_img;
    }

    Obviously that function does not return the wpmu image url that is needed, as the blogs.dir/blogid# is missing from the url.

    Could someone please help me with this?
