Hey, @Derek2020 .
Welcome to Shopify Community. My name is Olivia and I work here.
Thanks for sharing your question with our network. At this time, the Facebook Channel has a limitation of one image per variant, and no additional images. This is due to the way the channel syncs for shopping and how the integration is built-in to communicate.
As such, there are no workarounds to force additional images, but you do have full control over your feature images. Consider capturing photographs that provide a more well-rounded view of your products so as to encourage your customers to click-through to your site for additional views. Doing so can also increase your average order value and encourage repeat customers.
Alternatively, you can even get a little extra creative and create custom Facebook images for a 360 degree view by combining separate image views into one.
Let me know if you have any further questions around this.
Warm regards,
