RussianI ended up resolving this myself. Thank you for all the help.
This was a multi parter either way. I created a php cycler code Note** This code will actually run through all that was needed just in php. Sadly though as I wanted this to show up on a web page that would cycle on a timer I needed to use some javascript coding. This caused me to change parts of what was used. If you want to do the same thing you drop all code after you have created the pics array or you can even keep up to the point of the forwards and backwards array to be passed into javascript.
<?php
// create a variable to hold the directory location
$Dir = "..\Directory\pics";
// Variable to directory
$dirOpen = opendir($Dir);
// Need to start with a main array
$pics = array();
// Need two arrays for going forward and back
$forwards = array();
$backwards = array();
// Need variables for the program
$c = 0;
$d = 0;
$e = 0;
$i = 0;
$f = 0;
// Need to run through all files in folder and store into an array
while ($curFile = readdir($dirOpen))
{
if(strpos($curFile,'.jpg') !== false)
{
$pics[$i] = $curFile;
++$i;
}
}
closedir($dirOpen);
// declare variables to count previous opening of file
$a = count($pics); // number of pics in the folder
$b = count($pics) - 1; // need to account for starting at 0
// run through pics array fowards
while($f < $a)
{
$forwards[$f] = $pics[$f];
++$f;
}
// run through the pics array backwards
while($b > -1)
{
$backwards[$c] = $pics[$b];
--$b;
++$c;
}
// variables for the functions us
// use function for forward pics
/*function forward($array, $a)
{
$d = 0;
if($d == $a)
{
$d = 0;
return "pics/".$array[$d];
++$d;
}
else
{
return "pics/".$array[$d];
++$d;
}
}
function backward($backwards, $b)
{
if ($e == $b) // going to have a conflict with B becuase right now it should be at -1 or 0. need to compare to the value of -1 and have it reset to the max when reached.
{
}
}
*/
/*// Test the output of each array
foreach($pics as $imgs)
echo $imgs . "<br />";
foreach($forwards as $fors)
echo $fors . "<br />";
foreach($backwards as $backs)
echo $backs . "<br />";
*/
// $forwards and $backwards are the arrays to use for pics cycling
?>
To pass onto the java script I had to use the following code on another php page created to work with all html design of the main page.

var forwards = <?php echo json_encode($forwards); ?>;

var max = <?php echo $a ?>;
var count = 0;
function changePic()
{
document.myForm.pics.src='pics/' +forwards[count];
//document.myForm.pics2.src='pics/'+backwards[count];
++count;
if (count == max)
{
count = 0;
}
}
var start = setInterval('changePic()',5000);
</script>

Again PHPGlue thank you for all the help you offered. Hope this is useful for anyone else that wishes to do something similar. Please let me know if there are any questions on the code.
