so..your ajax data will look like this:
[img="http://lookpic.com/O/i2/1364/e8EIVxSr.png"]

now you can loop through data and populate array and list object..

[url=https://app.box.com/s/nozesa4msrfq346aoohpq8ovmaicxvic]phpDir2List.capx[/url]

if you upload a new videos or delete..even sub-folders in [b]videos/video[/b] folder..
you do not have to make any changes in php script or C2 code...

$size = array(4,2,1);[/code:2clsnhon]
in this case
[b]$size = array(Rows[/b](4)[b],Columns[/b](userName&userContact)[b],1);[/b]

php script to check [b]$size[/b]
[code:2clsnhon]<?php
$servername = "yourServerName.com";

$conn = new mysqli($servername, $username, $password, $dbname);

        if ($conn->connect_error) 
		  {
        die("Connection failed: " . $conn->connect_error);
          } 

$sql="SELECT * FROM Persons ";

if ($result=mysqli_query($conn,$sql))
  {
  
  $rowcount=mysqli_num_rows($result);
  $columncount=mysqli_num_fields($result);
            $size=( 'array('.$rowcount. ',' .$columncount.',1)' ) ;
            echo($size);
 
            mysqli_free_result($result);
  }

mysqli_close($conn);
exit();
