getHtml('Image caption', 'Image alt text'); // Display HTML echo $html; ?>
getHtml(null, null, $width, $height); // Display HTML echo $html; ?>In this example, the `imagecreatefrompng` function is used to load an image from a file. The `imagesx` and `imagesy` functions are then used to determine the width and height of the image. The `getHtml` method is called on the image object, passing in the image dimensions and null values for the caption and alt text. The resulting HTML is stored in the `$html` variable and then displayed using `echo`. Package/Library: The Image class and the `getHtml` method are part of the GD library, which is a PHP extension that provides functions for working with images. The GD library is included with most PHP installations and does not require any additional packages or libraries.
