take a look at the atachment this show when i try to upload some inmages and rescale them and write in different of /folder_in_root/folder_sub/folder_sub_sub that is accessible from the site what user and password is needed there is one for this path backoffice, it's protected with htaccess but they doesn't seem to work, all the FF freezes
i have figured out, there are another posts, the cause is basic authentification, flash doesn't pass it, so i put the uplad.php outside of the protected directory and implement a session-manner check
