can't delete created file(s)

[BroChris]

Trying to get a simple image gallery working. The code does exactly what I want it to do, but I noticed that after it creates the thumbnails, the thumbnails cannot be deleted. Any idea why? Here's the code:

<?php

ini_set("max_execution_time", 5000000);

$width=100; 	  // width of thumbnail size
$row = 4;       // number of rows in the thumbnail table
$quality = 70;

$dir = ".";
$result = opendir($dir);

echo("<b>Admin</b><br><br>\n");
echo("<form method=post action=admin.php>\n");
echo("<select name=convert_dir>\n<option value=no>Select a directory\n");

while ($fn = readdir($result))
{
 if ($fn != "." AND $fn != ".." AND is_dir($fn) AND !strstr($fn,'thumbnail_'))
 {
  if (!is_dir('thumbnail_'.$fn))
  {
   echo("<option value = \"$fn\">$fn\n");
  }
 }
}

closedir($result);

echo("</select><br><br>\n");
echo("<input type=submit value=\"Make Thumbnail\">\n</fonm><br>");

if (isset($_POST['convert_dir']) && $_POST['convert_dir'] != 'no')

{

  $dir = $_POST['convert_dir'];
  $opend = 'thumbnail_'.$dir;
  @$opend_result = mkdir ($opend , 0777);
	
  if ($opend_result)
   {
    $result = opendir($dir);
    while ($fn = readdir($result))
		{
    if ($fn != "." AND $fn != ".." AND !is_dir($fn) AND stristr($fn,'jpg') )
	
    {

    // Resize Photo

    //echo ($fn."<br>");
    $size = getimagesize($dir."/".$fn);
    //echo($size[0]." ".$size[1]."<br>");
		
    if ($size[0] <= $width)
     {

     //copy
     $copyfile = $opend."/".$fn;
     $original_file =$dir."/".$fn;
     copy($original_file , $copyfile);

    }
		
    else
		
    {
     $factor = $size[0] / $width;
     $new_length = intval($size[1] / $factor);
     $src_img = imagecreatefromjpeg($dir."/".$fn); 
     $dst_img = imagecreatetruecolor($width,$new_length); 

     $src_width=imagesx($src_img);
     $src_height=imagesy($src_img);
     imagecopyresampled($dst_img, $src_img, 0, 0, 0, 0, $width, $new_length, $src_width, $src_height); 
     imagejpeg($dst_img, $opend."/".$fn, $quality); 
     imagedestroy($src_img); 
     imagedestroy($dst_img); 
    }
		
		
   }
  }
 closedir($result);

 echo("<br><br><b>Done!</b><br>");
 }

}

?>

I tried deleting the files both through ftp and cpanel. I'm really stumped on this one...help!

Sure you have permission [The file is CHMOD'd 777]?

[firepages]

its all about ownage when PHP creates the files it (or rather the webserver) owns them , you the user no longer own them and therefore can not do anything with them unless they have the right permissions set.

so 2 options ,
1) delete via script (as the script `owns` the file) , <?unlink('filename');?>
2) when you create the thumbnail, chmod it to something accessible at creation time <?chmod(0777,$dst_img);?> then you can still delete via FTP/SSH/Cpanel.

Works great, THANK YOU!!!

Still trying to customize this script for my needs, ran into another issue.

I'd like to put the scripts into a different sub-directory than the images. What's the right way to reference the other folders?
