Add a static image on PHTML page and CMS Blocks : Magento2

image url Syntax is ok for both static block and phtml, But make sure that 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 your 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.

In your case,

<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.

And don't forgot about "[quotation marks]

For your 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">

Easy solution:

1. Put your image on Your Magento 2 Path:

   /app/design/frontend/< Vendor >/< theme >/web/images
   

2. Use this code to call the image in phtml file:

   echo $block->getViewFileUrl('images/demo.jpg');
