I cannot find where in the salesforce.com UI I can add a trigger on a file attachment. I can find triggers on almost everything else, but attachment seems to be missing from the list (even when I view source on the page and search it. Does anyone know WHERE I can put this trigger in?

There is no way to do it directly as Attachment is one of those "lesser" objects that salesforce really gets "protective" about in a random and biased way. The only "legit" way to do it is to use some external build&deploy tools such as Force.com IDE.

If however you are not a stranger to undocumented 'hacks' do the following. Go to any object's trigger list and click create new. In the URL locate entity query string parameter (e.g. entity=Case) and change it to Attachment (entity=Attachment) and press Enter. Newl loaded screen will accept Attachment trigger.
