gattach

Doing for Gmail what the MailTo link does for Outlook, the wonderfully simple gAttach is a small utility that reassigns Gmail as the default mail account from Windows documents. With gAttach installed, selecting Send from Windows Explorer, Firefox, and Microsoft Office automatically attaches the files to a Gmail composition instead of opening a new e-mail in your mail client.

Though effortless, we wish we could associate some file types with gAttach and let others default to the e-mail client. Also missing is a way for gAttach to automatically divide, where possible, e-mail compositions that breach the 20MB upload limit.
