IIS doesn't understand ".." at the beginning of resources. How to fix?

Question

PHP

The following pieces of code are used throughout the project. But images and css with js are not loaded like this. Everything works on the live server. There is no local for debugging.
<img src="../../../images/lp/lpn2.png">
And what else would you recommend for setting up on a local server? And is it worth making all these links of this type in the project
<img src="<?php base_url()?>/images/lp/lpn2.png">
