Lazy Loading with Thumbnails

$image = new Image('/path/to/files', 'https://mywebsite.com/', 'thumbs');
$image->lazy = true;
$image->targetWidth = 800;
$image->cacheLife = 3600;
$image->load('media/photo.jpg');

$pic = $image->getPic('Photo');
echo (string)$pic;
// src points to thumbnail, data-src points to original

Creating Thumbnails

use JDZ\Image\Thumb;

$thumb = new Thumb('/path/to/files', 800, 'thumbs', 3600);
$created = $thumb->thumbImage('media/photo.jpg');

echo $thumb->thumbFile; // 'thumbs/media_photo-800.jpg'

Watermark Protection

use JDZ\Image\Copyright;

$copyright = new Copyright('/path/to/files', 'protect', 'watermark.png', 'repeat');

$copyright->protectImage('media/photo.jpg');

// Restore original
$copyright->unprotectImage('media/photo.jpg');

$fs = new Fs('/path/to/files', 'media', 'thumbs', 'protect');
