friday afternoon question (i hope !!) foreach on view

[eluser]GSV Sleeper Service[/eluser]
get_filenames() was returning an array of arrays. so your original foreach was walking through your array of arrays and plucking out a single array entry one at a time.
each of those array entries contained a key (eg [0]) and a value (eg "gIMGP1741.JPG")
I suggest you follow pyromaniacs advice and try the following to get a better idea of what was going on.

Code:

<?php
foreach($filename as $p):
var_dump($p);
endforeach;
?>
