Good news for users of our Android app: The latest version now supports image uploading directly from your mobile device. If your calendar has an active Premium subscription, you may use this feature in your event editor.
Once the uploading icon is tapped, you get to choose to upload from Gallery and select an image or upload directly from your device’s Camera. The inserted image would be initially displayed as the link address in the event editor, and will be changed to a clickable link once you have saved it.
Supported file sources for uploading are currently limited to Gallery and Camera. More sources will be supported in future updates.
