I would like to generate to generate some kind of automatic alt attributes for the images, if they don't have alt set up.

Found this code, but it doesn't work for some reason:

function add_alt_tags($content)
{
    global $post;
    preg_match_all('/<img (.*?)\/>/', $content, $images);
    if(!is_null($images))
    {
        foreach($images[1] as $index => $value)
        {
            if(!preg_match('/alt=/', $value))
            {
                $new_img = str_replace('<img', '<img alt="'.$post->post_title.'"', $images[0][$index]);
                $content = str_replace($images[0][$index], $new_img, $content);
            }
        }
    }
    return $content;
}
add_filter('the_content', 'add_alt_tags', 99999);

Maybe not the best solution, but did it like this:

function add_alt_tags($content)
{
    global $post;
    $content = str_replace('alt=""', 'alt="'.$post->post_title .'"',
    $content);
    return $content;
}
add_filter('the_content', 'add_alt_tags', 100);
