Hi Belinda. Thanks for your pre-sales question about the Facebook Events Add-On.
The answer is yes. It does import each Facebook event’s image and description/details.
The intro video at https://theeventscalendar.com/product/facebook-events/ demonstrates the wp-admin import area but not a single event view or the front-end view so I understand the source of your question.
If you’re interested, you can check out the New User Primer for the Facebook Events Add-On for additional information about importing.
Please let me know if you have any other questions or if this resolved your issue.
