Thank you so much.

OK, what you've forgotten to do is escape the single quote marks you use in your javascript. Put another way you've got end quotes inside your echo statement that make the php interpreter very confused when it encouters more text after them.
Simply replace each ' with a \' inside whatever you're echoing.
echo 'thePics[10] = 'http://clan-d2k.net/siteimages/images/random/10.jpg'';
would become:
echo 'thePics[10] = \'http://clan-d2k.net/siteimages/images/random/10.jpg\'';
Got it?

your echo stops here 'javascript

2 solutions : or you start with echo "<center>
and end with </center>";

or you make it 100 % html: leave echo ' at the top
and the '; and the end

OR just clsoe your PHP brackets before this and reopen them after...

so like
Some PHP
?>
all your javascriipt stuff you are echoing
<?php
more PHP

much easier sometimes and saves adding a ton mor Chars to your files,

Also the <center> tag has depreiciated so you are better using something like <div> and using CSS to center..
