Delete Gmail Attachments

I'm a graphic designer, and I wind up sending people loads of fairly large, high-resolution attachments. All these hefty messages sent over the course of a year or two are clogging my mail box, and my Gmail account is just about completely full.

It's be nice if I could just tell Gmail to delete these attachments, but apparently there is no way to do this. Google is well aware of this problem, as its users can attest, but has no interest in solving the problem. Instead, we get delightfully useless features in Google labs like a snake game.

The only solution users have come up with is to send the message to myself. Of course, this won't work for hundreds of e-mails clogging my account, and when I try to search for the message, the date will now be messed up.

Seriously, Google. Either give us the option to delete attachments from old, sent mail, or triple the room we have to store the junk you apparently won't let us delete.
