Hi Andrea,

This is a customization question and support doesn't offer customization services as we wrote on our support homepage and on this area. I will try to help you this time though

That is not possible but I can give you a code to do that. Can you please add the code below to your Custom CSS area:

section.blog .post .post-image {
    display: none;
}

If you're looking for professional help in this matter, there's always someone available for such tasks on the WP Kraken or Envato Studio. Pricing and timeline are always straightforward there and that's the main reason for recommending those services.

Have a great day!
