You might notice that when sharing your new event to social media it might be using information or images from an old event. This is something we will fix in a future update, however, you can fix it for your event right now! Just follow these steps:
1. Upload your social media image for your event under the control panel

2. Visit https://developers.facebook.com/tools/debug/og/object/

3. Enter the URL to your event's homepage in the box labeled "Input URL"

4. Click the "Fetch new scrape information"

This will force Facebook to look at your event and update with your new event image and information.
