The `the_post_thumbnail` function is called in `template-parts/content. php`. It not advised to edit the theme’s files directly, but to use a [child theme](https://codex.wordpress.org/Child_Themes) to apply the modifications. * Thread Starter [csandreas1](https://wordpress.org/support/users/csandreas1/) * (@csandreas1) * [8 years, 8 months ago](https://wordpress.org/support/topic/need-help-using-this-plugin-on-posts/#post-9512761) * the code is here, i am trying to replace parts with the code you posted in your first post but the image dissapear i am replacing this * ``` ' : ''; the_post_thumbnail( 'tyche-blog-post-image' ); echo ! is_single() ?
