How to edit default post settings

I want to delete content block and add custom fields for image, like on this screenshot.

I don’t want to add custom content type, I just want to edit defalt post type.

Any solution?

Refer to the manage_posts_columns filter, and also the manage_posts_custom_column action.

Here is a really old tutorial, linked from the Codex, that might be instructive. (Caveat: it’s from 2007; some things might be out of date.)

Edit

The above hooks are for the manage posts screen. To remove/add meta boxes to the edit post screen, see add_meta_box() and remove_meta_box(), which can be invoked inside a callback function hooked into add_meta_boxes.

Here’s a tutorial for customizing meta boxes on the edit-post screen.

I found something:

add_action('init', 'remove_editor_init');
function remove_editor_init() {
remove_post_type_support('post', 'editor');
}

And it’s working for me 😉 thanks guys
