-- Image path
- when you write this code in static block
<img src="{{view url="images/slide-bg.jpg"}}" alt="test" />

on front end it looks like
http://localhost/magento2new/pub/static/frontend/Magento/luma/en_US/images/slide-bg.jpg

Where Magento/luma is package name and theme name, you can replace with package and theme name
So you have to take care for  slide-bg.jpg is exist in pub/static/frontend/Magento/luma/en_US/images directory.

- when you write this code in phtml file

<img src='<?php echo $this->getViewFileUrl('images/footer-logo.png'); ?>' alt="Demo">

Syntax seems ok , but in frontend It looks like 
http://localhost/magento2new/pub/static/frontend/Magento/luma/en_US/images/footer-logo.png

So you have to make sure that footer-logo.png exist in pub/static/frontend/Magento/luma/en_US/images directory.

- For custom module create a directory structure like Company/Module/view/frontend/web/images/image-icon.png
and in phtml use following code

<img src='<?php echo $this->getViewFileUrl('Company_Module::images/image-icon.png'); ?>' alt="image-icon" width="30" height="25" />
- OR -
<img src='<?php echo $this->getViewFileUrl('Magento_Newsletter::images/envelope.png'); ?>' alt="image-icon" width="30" height="25" />
