What is the current behavior?

In the template detail page, all image covers have border-radius.

What is the new behavior?

We don't want to add border-radius to all images on the template detail page. To achieve this, I removed the border-radius from the <img /> tag and replaced all .jpg images with .png. These .png images have their own border-radius.

fine result:
