Please perform the following steps to enable auto-publishing of assets:

Locate the config file /App_Config/Include/damforsitecore/DFS.Connect.config.
Find this area <event name="item:saved">
The handler with the method OnItemSavedPublish is by default disabled. Enable it and reload the site

How it works

If you manually synchronize the silo, the items won't automatically be published to web.

You have to publish the silo manually, but the background process which keeps the silo up to date will automatically publish any changes to the web database

It is required that the asset silo item (sitecore → media library → Digizuite → assets silo) has been publish to web before this feature is enabled. Otherwise the assets wont be auto published.
