Valerio, 
 
I 
think that most people just set up a cron job or a scheduled job on their server 
to delete all of the temporary images at some periodic interval.  (e.g. 
24hrs, 12hrs, 1hr)  Your interfval would depend on the number of images 
that you are generating, disk space, etc.
 
In the 
code that you use to delete the files, you may want to look at the timestamps on 
the images and only delete images that are at least 1 minute old, so you don't 
accidentally delete an image before it can be used by the page that called 
it.
 
David.

      Thanks for the quick reply,

When you run this 
        function? after each requests ? but if so, the client is able to read 
        the image before you delete it ?

best 
        regards,

Valerio

                Dear 
                all,

I have a demo where I'm using mapserver cgi 
                interface. I'm using the browse mode so each time mapserver 
                receive a request, it creates a temporary png on the server 
                filesystem. 

Do you know how and when i can delete those 
                temporary image since they are used only one time ?  
                

An attacker could easily  fill all the server 
                HD  locking all the 
              system.

Thanks

Valerio
