Attachments Panel
The Attachments Panel is only available if an S3 Attachments bucket has been configured and a suitable bucket has been selected using Manage > S3 Bucket for Attachments.
Files can be added as an attachment to individual assets or the entire collection. Attachments will stored in the configured S3 bucket. These can be downloaded from the attachments panel as well. Removing them only removes them from the panel, not from S3.
