they do not have ftp or php,mysql settings yet. they do plan to get ftp soon though.
you need to change the main page for it too work but it will.
to get images and a css then upload the images somewhere and in the css where it has the url(then the /images/image name) change that too url(http://theimagelink.com/the rest of the link)
and put the css into your html like with this code.
<style type="text/css">
then the entire css.
close it with </style>
you then have all the images load and the css will load fast.
im doing it but i cant run the server 24/7 cause i set it up at school but it does work.
the only thing i havnt figured out is the domain names. you need to use a dns service like no-ip but i think you need to port forward for no-ip.
