Import ISO domain? I think you want to attach it, not import it.

You should see the button if you open the correct tab:

1. On the left pane, click the data center name (Frankfurt)
2. Select the "Data Centers" tab in the top right
3. Select the "Storage" tab in the bottom

You should see the "Attach ISO" button in the top of the Storage tab.

See the attached screenshot (from 3.6, but it should be similar)
