Paul,
the warning that John refers to does occur - whether you see it
depends on the error reporting level, PHP will create the array for you
if you have not already initialized it but a warning will be generated
in such cases. - errors that may not display on one machine might be
visible

Spotted this problem when staring at your code.
Number of open braces: 2
Number of close braces: 1
You need to close off your while loop.
Should I
You didn't close your loop;
while ($file = readdir($dh)){
if (strstr ($file, '.jpg')){
$pictures[] = $file;
}
#vardump ($pictures[]);
} = here
?
instead of;
while ($file = readdir($dh)){
if (strstr ($file, '.jpg')){
$pictures[] =

The while function has nothing to do with it. Using the syntax $array[]
simply adds an element onto the _end_ of the array and PHP picks the
next logical, numerical index.
OK thanks

Totally ignorant need for clarification... Should I set up a counter for
loops $integer++ or if I'm going through something, the while function
knows to just go through those and fills in array numbers accordingly?

OK thanks again for helping through the stumbling blocks... I'm rolling
again now.

Just make sure $pictures is defined as an array before you try to push a
value onto it (even using the method you have now), otherwise you'll get a

It seems to be working fine this

So when assigning values to an array inside a loop, it knows to advance
to the next but then if I want to print those out at the same time, it's

while ($file = readdir($fh)){
if (strstr ($file, '.jpg')){
$pictures[] = $file;
