Hi Christian, the reason why your email isn't showing images is because the images are locally saved in the image folder from the downloaded zip file from BeeFree. You'll have to import those images as well and update the image URLs.
For importing your email from BeeFree into Outlook, we recommend instead to follow these instructions:
1. Send your email message created in BeeFree to your Outlook inbox using the "Send test" feature (from top-left menu)
2. In Outlook, select the email and click on "Forward"
3. Remove the extra spacing at the top and the signature in the footer
4. Edit your subject line
5. Enter your email recipients and send it
Hope this helps!
