Create Open Graph images (og:image, twitter:image, vk:image) for each (or some) site pages.

Use page title to create an eye-catching page preview when users share the link on social networks or instant messengers. Learn more about Open Graph.

Features:

Image generation with your text and site name
Fully customizable (see configuration)
Small image size (15-50 Kb) with high resolution and quality (check it)
Aspect ratios presets for popular social networks

▶ See examples

Requirements

PHP 7.4 - 8.3
The Imagick PHP extension

Installation

You can install the package via composer:

composer require abordage/og-images

Quick start

use Abordage\OpenGraphImages\OpenGraphImages;

require __DIR__ . ' /vendor/autoload.php';

$config = ['app_name' => 'alice.wonderland'];
$text = 'The adventures first, explanations take such a dreadful time!';
$path = __DIR__ . '/your-name-for-image.png';

$openGraphImage = new OpenGraphImages($config);
$openGraphImage->make($text)->save($path);

Note
All images are encoded in PNG format as it provides the best ratio between size/quality. For the same reason, the package uses the Imagick driver - in tests, it showed an advantage in speed and final size of the generated images.

Usage

$openGraphImage = new OpenGraphImages($config);

// for <og:image>
$openGraphImage->make($text)->save($path);
// or
$openGraphImage->make($text, 'opengraph')->save($path);

// for <twitter:image>
$openGraphImage->make($text, 'twitter')->save($path);

// for <vk:image>
$openGraphImage->make($text, 'vk')->save($path);

// custom size
$openGraphImage->makeCustom($text, 600, 400)->save($path);

After generation, you need to somehow organize the relationship of images with a specific page (for example, attach to a model). If you already have a solution ready to accept an image and attach it to a specific page, you can get the image as a string instead of saving it:

$openGraphImage = new OpenGraphImages($config);
$imageBlob = $openGraphImage->make($text)->get();

If after generation you need to get sizes of the image, you can get it as follows:

$openGraphImage->make($text, 'twitter')->get();
$imageSizes = $openGraphImage->getImageSizes();
// return [
//    'width' => 1200,
//    'height' => 600
// ];
