Question: Can each topic have cover image to look topic list page like image gallery?

I'm not sure if I explained properly but I really wanna use this feature.
I think it's possible but I'm not sure if I can do this by myself lol

What I'm saying is that it's normally list of topic subject Text Only when you click any forum categories.
But it will be much better if topic list showing with each topic cover image(preview image), for example, for viral photo categories.
Just like pinterest grid layout.

Can I know if this feature is easy to implement?
And can anyone possibly show this feature if already using on your forum?
