@GKotta.
If your use case is to delete images (irrespective of user) after two
months, then cron Or timer job on server (Check Quartz) is the good
way to go. Remember in this approach you wont have access to user
session.

If you need User Session to decide whether to delete or not , then you
can use SessionListeners on Server side.
Google for SessionListeners to know more about its use cases.

For sending mails , use javax.mail as per @mike's reply.
Hope this helps.

Prakash M.
