I’m assuming this question is in relation to the Default Entry Card template, correct?
If it is, the you can use CSS to change the image shape. Here’s a link to developer doc which may help:
This actually covers how to use CSS to to have a “default image”, but you can use the same CSS selector to create a circle by uncommenting the border-radius parameter.
You can control what is displayed in the Default template By using the Template Customizer.
Navigate to the Connections : Templates admin page and click the Customize button for the Default Car template.
The page will refresh displaying the Customizer on the left and a preview on the right.
Uncheck the Categories item and click Publish.
Now, in the preview, click an entry name. It does not matter which. The preview will refresh displaying the single entry view of the template.
Uncheck the Categories options again and click Publish.
Now exit the Customizer.
Hope this helps, let me know!
