Hello antiknatur,
There is not an option to specifically remove the post picture from the post but it can be hidden via CSS.
To remove featured image from blog single post via CSS, please log in to the admin area and go to “Appearance >> Customize >> Additional CSS”.
Paste the below code in “Additional CSS” and save it:
.single-post .content-area .featured-thumb{
display:none
}
Hope this helps!
Thank you
Regards,
