Calendar events are often comprised of more than just a date and a time. It is often necessary to include event-related documents such as meeting agendas, travel information, instructions to perform the job or a pictures of goods delivered. It is therefore useful to be able to attach files and pictures to the calendar event.

Teamup Calendar allows you to upload such images and documents to an event. Images are displayed and documents are linked to the event. Attaching a file to an event is as simple as attaching it to an email.

Inserting files stored on Dropbox is free to all users.  To do so, simply click the Dropbox icon.  If you would like to upload files and images to Teamup’s file servers, a Premium subscription is required. If you are currently on a Free or Plus plan, it’s easy to upgrade to the Premium plan. You can try this feature in the Live Demos, which have the Premium features enabled.
