Here's how I'd do it...and it has nothing to do with GWT. You server side impl class is just a java servlet with a bunch of methods (assuming here...). At the beginning of each method, add a call to another method, call it checkAndDeleteImages().. Inside that guy, go to your database with today's date and query all images that have a creation date (or something similar) of today - 2 months. Get those images (blobs?, strings?, what?) and fire up good old javamail (javax.mail.Message in particular), create a message (probably MimeMultipart if I remember correctly for the attachment), point it at a valid SMTP server and send. When complete, delete the images.
Add this method call to every server side method call....sometimes you'll check seconds after checking...if that's oppressive, create a stateful bean on your app server with the timer. Don't try to do this in your client code...you'll go nuts and cause yourself a bunch of head aches, in my opinion.
