Joomla: $this->baseurl is not working in custom template module

Joomla provides some basic themes which are already installed in the templates folder. When any developer develop the CMS in the joomla , he use his own template with new design.
On the index page

$this->baseurl

works well but when he want to own module then he create a folder in custom template folder.
But in that module folder

$this->baseurl

doesn’t work. Why? because joomla does not provide to access $this in the custom module folder.

You should replace below code

<img src="<?php echo $this->baseurl; ?>/templates/CUSTOM_TEMPLATE_NAME/images/xyz.jpg" alt="" />

to

<img src="<?php echo JURI::base(); ?>/templates/CUSTOM_TEMPLATE_NAME/images/xyz.jpg" alt="" />
