Ok, well..... http://pagesofinterest.net/code/of_interest.php
That actually gives you access to his code. Place that, do whatever it says you need to do to make it work. I didn't really look at it, just went to see if the source was available as the outside link your trying to include is a script, and most scripts, crons and such, tend to display blank pages. The one in your first include does just that. Place the source file on your hosting account.
this applies to the first and second part, if you have all the files on your account. say, as an example, your accounts at /home/exampleuser/example.com - you could put the files in /includes in there and then call then through php with include('/home/exampleuser/example.com/cloud_creator.php'); and so on.
Obviously, i only mention because you just showed source and not much else, these need to be in whateverscript.php otherwise it wont parse the include.
on your first example, change the <? to <?php as well, as <? is sort of non-standard now and i believe it might be considered obsolete. It's been a while since I've looked in to it.
