Any php wisemen?

specifically in a php block of simple portal 2.3.5 in Simple Machines Forum 2.0.7.
I want to display a random image from a folder.
Code:
$dir = 'http://mywebsite.com/random';
$images = glob($dir. '*.{jpg,jpeg,png,gif}', GLOB_BRACE);
$randomImage = $images[array_rand($images)];
echo ' ';
?>
Huh. The inequality brackets apparently work even when in a code-box... the code that is not displayed is:
inequality-bracket img src="'.$dir.$randomImage.'" width=89 inequality-bracket
Meh. It only displays a missing image placeholder, not unlike the one echoing above  .
It's so simple... yet so not working.
Any help?
p.s. I couldn't post this subject line because it says no profanity...
"Any php gurus?"
LOL... what profanity? Is php so bad it's a three letter four-letter-word?
edit: oh...

I think that $randomImage already includes your $dir because you included it in your glob() call.
I think your code should be...
echo '{img src="'.$randomImage.'" width=89}'
(replace curly braces with less-than/greater-than)
I believe this will also work...
echo "{img src=\"$randomImage\" width=89}"
(again, replace curly braces with less-than/greater-than)
Try this. After your glob() call, add this line...
print_r($images);
...And look at the output.

all I get is

That's the frustrating part. The directory is correct, and is full of goodies.

Nailed it! Ah. I knew I had to be overlooking something ridiculously simple.
Changed
$dir = 'http://mywebsite.com/random';
to
$dir = '../random/';
and BINGO! We got random pics!
Thanks krick!
