For inline images to appear in emails without being attached to them they need to be downloaded from a remote server when the message is opened. While Outlook likes to go the safe route of the attachment — remote images can not be displayed if no there is no net connection when the message is opened or if the remote server is down, and since they pose a privacy risk many users disable them —, it can also be configured to use references to remote images.
