The problem with this new theme

I just installed this theme called Yoko, by elmastudio.

It looks pretty and everything, but . . . . oops . . . . since I’ve used the banner image of each post as its thumbnail (because that’s how the old theme operated) . . . well, it’s like too much image duplication. And I am not a fan of this.

Although I am a fan of kitten randomly jumping up on chair arm and chirping at me.
