Featured/default image – none selected

Hello! I’m an artist with a website here:
https://www.leahjayart.com
— I’ve installed your plugin, but I can’t get it to work when it comes to customers sharing my product images.

For example, when someone goes to one of my galleries and clicks on an image, they are led to a page with Etsy-generated content on the left, and the Social Media Feather in a widget to the right on the sidebar. When you select something, such as the Pinterest button, this is the message I receive:
Whoops!
You need to upload an image or provide the ‘image_url’ parameter
Tumblr, same deal.

Weirdly, Twitter and Facebook do work. I suppose it is because those two are using links rather than needing a defined image?

My goal would be getting things to where I could assign a featured image to each individual product page somehow? Or perhaps figure out how to manually target individual product images in your plugin? I’ve noticed that some people have had problems with this issue earlier in the queue, but I’ve tried everything discussed and it doesn’t seem to be my particular issue.

I hope I can keep using your plugin with my current setup, because I really like the ease of use and clarity of it.

Thanks so much, for any advice!
