How to set image path in wordpress?

Question

WordPress

Good afternoon, maybe someone has come across this. While the wordpress site was on a PC, everything worked fine, the template contained lines like:

<img src="<?php echo get_template_directory_uri() ?> /img.jpg" width="300">

Pictures loaded without problems.
After transferring the folder with the site to the hosting, the pictures, written in this way in the template, stopped loading. Everything else (including pictures from posts) works fine. What could be the problem and how to set the path correctly?

Answer 1

if you have a child theme then use get_stylesheet_directory_uri()

Answer 2

get_template_directory_uri()
Gets the path to the folder template, inside the template you need to explicitly specify in which folder of the picture

Answer 3

Check the case of letters in image filenames. Linux hosts are very picky about this, unlike Win.
img.jpg != img.jpg
