Code for images in section required

Good day Grace Themes

I have another question regarding how to add a few images to a section in the Prevalent Theme. I have added the following code in a new section trying to add a few images to this section:
[subtitle color=”#111111″ size=”15px” margin=”0 0 50px 0″ description=”Popular Safari Destinations”]
[counter image=”https://www.meine-safaris-namibia.de/en/wp-content/uploads/sites/4/2020/02/swakopmund_deutsche_architektur.jpg” title=”Swakopmund” description=”Namibia’s favourite Holiday Destination” button=”Read more” link=”#”]

Obviously [subtitle color=”#111111″ size=”15px” margin=”0 0 50px 0″ description=”Popular Safari Destinations”] is correct. However, “Counter image” is not correct, as it displays the rounded image, but not a square image. I have tried “image” only, but that also does not display anything. Kindly advise the correct code for displaying images.

Thank you and kind regards
