Attach Files to Google Apps Calendar Events

Google Apps users can now add attach Google Documents and Picasa Web Album pictures to their Google Calendar appointments, helping to explain or illustrate shared events.

The attachment option, which might not be enabled for all Apps users, appears just below the description box. Perhaps that's an intentional suggestion that if that box is looking stuffed, a doc or picture with directions, meeting details, and other important details might be a more sensible and courteous route. For those already keen on Google's Docs and Picasa services, or those who really dislike Evite, this is a handy way of sending all-details-included party invitations—whenever it arrives on personal, non-App accounts, that is.
