In what scenarios would the gd2 library be essential for PHP development and how can its absence be mitigated?

The gd2 library in PHP is essential for image processing tasks such as resizing, cropping, and creating thumbnails. If the gd2 library is not available on the server, you can use a workaround by utilizing a different image processing library like Imagick. 

// Check if gd2 library is available
if (extension_loaded('gd')) {
    // Use gd2 functions for image processing
} else {
    // Use Imagick library for image processing
    $image = new Imagick('image.jpg');
    $image->resizeImage(200, 200, Imagick::FILTER_LANCZOS, 1);
    $image->writeImage('image_resized.jpg');
}
