PHP Photo Gallery Troubles

Hello... I've been trying to set up a PHP Photo Gallery and using Webmonkey to teach myself PHP. I've gone over this one several times and I can't seem to find what the glitch is. This is the page that pulls up when I try to look at my gallery online, which is at:

http://www.greyeye.com/photophp/

Here's what I get:

Warning: getimagesize(../images/thumbs/csh -c "ls *jpg > list.photos"): failed to open stream: No such file or directory in /u222/greyeye/photophp/index.php on line 46

What am I doing wrong?

I should show you lines 46 and 47, I suppose! Here they are:

$thumb_image_size = getimagesize($thumbnail);
$image_size = getimagesize(trim($photos[$i]));

And here's the larger section that it's part of:

//initialize variables
$data_file = "../images/list.photos.txt";
$thumbnail_dir = "../images/thumbs/";
$num_rows = 4;
$photos_per_row = 5;
$photos = file($data_file);
$total_photos = sizeof($photos);
$photos_per_page = $num_rows * $photos_per_row;
//check to see if the start variable exists in the URL.
//If not, then the user is on the first page - set start to 0
if(!isSet($start)){
$start = 0;
}
//init i to where it needs to start in the photos array
$i = $start;
$prev_start = $start - $photos_per_page;
$next_start = $start + $photos_per_page;

for ($row=0; $row < $num_rows; $row++){
print("<tr>n");
for ($col=0; $col < $photos_per_row; $col++){
if($i < $total_photos){
$thumbnail = $thumbnail_dir.trim($photos[$i]);
$thumb_image_size = getimagesize($thumbnail);
$image_size = getimagesize(trim($photos[$i]));
print("<td align="center"><
a href="javascript:photo_open('photo_display.php?photo=
".trim($photos[$i])."','".$image_size[0]."','
".$image_size[1]."');"><img src="".$thumbnail.
"" ".$thumb_image_size[3]."></a></td>n");
} else {
print("<td></td>n");
}
$i++;
}
print("</tr>n");
}

//end table

i would guess it's either a permissions issue on the working folder, or you've specified the wrong path that it's supposed to look in.
