[thelist] php image rotation problem

[php architect]

Your file might have blank lines in it. Maybe try.

$fp = file($file);
foreach($fp as $k=>$line){
 if( ! $line ){
   unset($fp[$k]);
 }
}

Also you could change 

$random_image = $fp[array_rand($fp)];

to

$key = array_rand($fp);
$random_image = $fp[$key];
echo($key);

That will at least tell you what line is being selected, if you
believe the problem is with an image.
