First Image plugin for Craft CMS 3.x

A plugin to get first image from Redactor Field.

Requirements

This plugin requires Craft CMS 3.0.0 or later.

To install the plugin, follow these instructions.

Open your terminal and go to your Craft project:
```
 cd /path/to/project
```
Then tell Composer to load the plugin:
```
 composer require by/first-image
```
In the Control Panel, go to Settings → Plugins and click the “Install” button for First Image.

There are two ways of getting first image from a redactor field:

{{ entry.body | getFirstImage }}

or

{% set image = getFirstImage(entry.body) %}

This will output the source of the first image found, which then can be used in <img> tag.
