The Pebble software doesn't have support for images in notifications right now. But it definitely could/should be added. And it's open source, so you could even do it yourself!

I am not familiar with the pebble SDK or notification API it has. Smart watches usually will display whatever notification the mobile devices instructs it to display.
If you get a push notification on your mobile, I don't see a reason why pebble won't display it. The thumbnail image might be fixed but all the text content will be shown. And FWIW, the entire thing is open source so you can go in an add it, or open feature requests, etc.
Use the Android pebble app "Notification Center" and it should be able to do that for you.
(Notification Center gives you extreme amounts of control over what to send to the watch how it gets displayed, etc. It's the reason I'm still daily wearing my pebble watches)
On my Samsung Galaxy watch, if I get a notification from my Unifi security cameras, for example, I get a little thumbnail image appear on my watch. There's no special app on my watch, just the app on my paired Galaxy phone.
Will it do this? Or would I just get a text notification? I don't understand smart watches well enough to know how much they are doing themselves vs how much of what they do is to be a mindless projection of whatever the paired phone tells them to do.
