Magento 2 – Get Image URL in PHTML File

image-urlmagento-2.1magento2magento2.2phtml

I'm trying to add an image to my first module can someone tell me how I cando this I am new to Magento

this is phtml file

<h2>Hello world</h2>

module is in

app/code/Test/Helloworld

This is my directory structure of Helloworld Module

For example your image at:

app/code/Vendor/Module/view/frontend/web/images/demo.jpg

Use $block->getViewFileUrl() function to get image url in phtml file like this

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

In the latest beta version for Magento 2 there is no more head block.
The head, content and other blocks are defined as containers.

should remove the <referenceBlock name="head"> section and instead add this inside the <head> tag (where you added the page title)

<css src="Magento_Hello::css/custom.css"/>

so your <head> tag should look like this:

<head>
    <title>Hello World</title>
    <css src="Magento_Hello::css/custom.css"/>
</head>

{{block class="Magento\Framework\View\Element\Template" template="Testing_Helloworld::helloworld.phtml"}}

you can use Magento\Framework\View\Element\Template block class to call custom phtml files with out define block class.
