In this little script:-
<?php
session_start();
//read folder
$folder=opendir(".");
while ($file = readdir($folder))
$names[count($names)] = $file; // <----- Line 8
Obviously $names won't be defined in the initial state the first time this line
is hit, thus count($names) would/should be undefined...
closedir($folder);
//sort file names in array
sort($names);
//remove any non-images from array
$tempvar = $i = 0;
These "shortcircuit" assignments aren't the best of things to do...
for ($i=0;$names[$i];$i++) { // <----- Line 14
Remember the undefined case up there, there just might not be a
index 0, be rather an index "undefined" ....
Don't we just *love* these interpreted languages and their "funnies" :)
I keep getting:-

Please tell me what evil I have committed to cause this?
