I would try to provide the best ergonomics and therefore I'd have logo upload in the second step. When uploaded, place the image in a temp. folder under the <sessionId>.gif name or something like that. When the wizard completes, place the uploaded image in the right place and remove it from the temp. dir. Also, if you have 'cancel' button in your wizard, bind it to CleanAction or something like that. Also, servlet spec 2.3 defines some session listener classes which could be used to periodically check the temp dir and the active sessions (no active session -- delete the file). And, of course, simple cron job which deletes temp files older than X hours is a must. -- [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
