I seen that tutorial. theres no way to avoid downloading the image to me server?  Im trying to avoid that. If i have 10,000 users come to my site and 2000 image are bad images because they downloaded the wrong one. then i have to delete 2000 images.

well, you can delete the image if the user click on "delete image" button (using php) , I don't think it would be a problem with PHP. of course you won't delete those images yourself manually, let the php do it for you

in that case, you can delete the file using php easily using php

unlink('D001_image.jpg');

or
$dir = "/path/to/images";
$file = "myImage.jpg";
 unlink($dir . "/" . $file);

Here is a link of a complete explanation about unlink function

Hi

To delete all files of a particular extension, or infact, delete all with wildcard, a much simplar way is to use the glob function.  Say I wanted to delete all jpgs .........

<?php

foreach (glob("*.jpg") as $filename) {
   echo "$filename size " . filesize($filename) . "\n";
   unlink($filename);
}

?>

also

To delete files using wildcards:

<?
function delfile($str)
{
   foreach(glob($str) as $fn) {
       unlink($fn);
   }
}
?>

i read that already, but do i make $str = "the name of the Folder"

<?
function delfile($str)
{
   foreach(glob($str) as $fn) {
       unlink($fn);
   }
}
?>

will this delete the "Folder" from the server?

not at all :)
but i think the code you want is in the same page

<?php

function remove_directory($dir) {
  if ($handle = opendir("$dir")) {
   while (false !== ($item = readdir($handle))) {
     if ($item != "." && $item != "..") {
       if (is_dir("$dir/$item")) {
         remove_directory("$dir/$item");
       } else {
         unlink("$dir/$item");
         echo " removing $dir/$item<br>\n";
       }
     }
   }
   closedir($handle);
   rmdir($dir);
   echo "removing $dir<br>\n";
  }
}

remove_directory("/path/to/dir");

?>

hope it works

if someone uploads a picture to my site. when they preview it. if they dont like it i use php to delete it from my "Tempupload" folder.

After 30 days when their time is up. i can write a php file to delete their whole folder from my site.
