Bug description:  Function ImageJPEG can't open temporary file if image filename is 
not specified

Even with all directory permissions set right for user
IUSR_NTMACHINENAME (the user with which some person will access my website through 
IIS) I always get the following message when trying to generate an image without 
saving it to disk:

Warning:  imagejpeg: unable to open temporary file in 
C:\InetPub\MyWebDirectory\file_that_generates_the_image.php on line 76

Can somebody confirm that under NT there is no way to create a temporary image file? 
(Perhaps when uploading a file through PHP under NT the same problem should occur?).

I also verified if there was some problem with permissions relating the temporary 
upload directory setup in PHP.INI, and even changed this directory to be the same as 
the one reported by the browser with no success (that is, I setup this temp upload 
directory to be the same as the one where my script is running - just for testing 
purposes, since this would not be an acceptable solution).
