**Yes.** The **GD** graphics library is available for PHP on Ruachost hosting.

GD lets your PHP scripts create and edit images. It's commonly used to:

- Resize uploaded photos and create thumbnails.
- Add watermarks or text to images.
- Draw charts and CAPTCHA images.
- Convert between formats such as JPEG, PNG, GIF and WebP.

WordPress, WooCommerce and many other applications use GD (or ImageMagick) to create image sizes when you upload media.

```php
<?php
$img = imagecreatefromjpeg('photo.jpg');
$thumb = imagescale($img, 300);
imagejpeg($thumb, 'photo-thumb.jpg', 85);
```

## Check that GD is switched on

If you see "Call to undefined function imagecreatefromjpeg()":

1. Log in to cPanel.
2. Open **Select PHP Version**.
3. Click **Extensions** and make sure **gd** is ticked.
