Why is it giving an error and not uploading some pictures?

Question

WordPress

My paths are relative:

<img src="assets/img/logo/sajooo.png" alt="">
<img class="nav__search" src="assets/img/icons/serch.png" alt="">
<img class="nav__basket" src="assets/img/icons/shop_box.png" alt="">
<img class="nav__lk" src="assets/img/icons/li.kab.png" alt="">

I tried to set paths through the domain, they still did not load. Example:

<img class="nav__basket" src="https://Domen.com/assets/img/icons/shop_box.png" alt="">

Answer 1

<img src="<?php echo get_template_directory_uri();?>/assets/img/logo/sajooo.png" alt="">
<img class="nav__search" src="<?php echo get_template_directory_uri();?>/assets/img/icons/serch.png" alt="">
<img class="nav__basket" src="<?php echo get_template_directory_uri();?>/assets/img/icons/shop_box.png" alt="">
<img class="nav__lk" src="<?php echo get_template_directory_uri();?>/assets/img/icons/li.kab.png" alt="">

Use the function <?php echo get_template_directory_uri();?> to form the correct path
