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...
Or am I missing something?
