<?
    // root path to browsable/uploadable directory
    // e.g. <a href="http://www.mydomain.com/uploads" target="_blank">http://www.mydomain.com/uploads</a> 
    $rootURL = "/uploads";
    
    //prefix that appears before file name when browsed for e.g. localhost
    // e.g. <a href="http://$URLprefix/uploads/mypic.jpg" target="_blank">http://$URLprefix/uploads/mypic.jpg</a>
    $URLprefix = $_SERVER['SERVER_NAME'];
    
    // debug.  if true also writes output to a file in executing directory
    $debug = false;

    // Hello 
    //
    // This is my first attempt at helping with an open source project so
    // please bear with me.  I've written this connector as i want to use the
    // FCKEditor in my site because it will be an excellent piece of software.
    // if this helps move things along, brilliant.
    // 
    // This connector handles File browsing & uploading however it does not
    // check permissions or if the filename is valid.  Please feel free to add
    // this yourself if required.
    //
    // I hope you find this useful.
