I removed your attached file. Don't post config files with passwords and salts in
If I try to login on your site, I get:
Fatal error: require(): Failed opening required '../config.php' (include_path='.:/usr/lib/php6') in /homepages/33/d385827780/htdocs/moodle2/login/index.php on line 27
...which implies a path is wrong somewhere. What I don't understand is why you are using a 1.9 style config.php for a Moodle 2.4 installation. 2.x doesn't have a $CFG->dirroot setting for example. You are probably best to copy config-dist.php to config.php, edit it and set everything fresh. Check those paths carefully.
Anyway, enable Debugging (right up to Developer) on your site, right click on one of the missing images and view it in a new tab or window. You should get an error message. What is it?
