Sounds to me like the best solution for you would be to make your own session-handling routines... This way you'd have complete control over your sessions... -- Lasse -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Depending on the sizes of the files, number of users, etc... Do as you do now, and then do a scan of the temp files in one of your scripts and delete any older than a reasonable amount of time... 24 hours for example Don't your sessions time out BTW? That should make it possible to check for any temp files whose session isn't alive anymore and delete them. Since the corresponding session is dead anyway the image can be safely deleted...
