How do I hide images used in the loop from the single page?

Okay so here’s the site: https://gawkr.co.uk/
It uses this theme: https://www.ads-software.com/extend/themes/tanzaku (good fun)
This theme doesn’t not use featured images, instead I add an image to the body of the post and it’s displayed in the loop. Problem is, it’s also being displayed when viewed as a single post.

How do I hide an image from the single post?

Thank you anyone who knows
