How can the use of realpath() impact the loading of images in a PHP application?

Using realpath() can impact the loading of images in a PHP application by resolving the full path of a file. This can help prevent issues with relative paths and symbolic links that may cause images not to load properly. By using realpath() when specifying the path to the image file, you ensure that the correct path is always used, resulting in successful loading of images. 

$imagePath = '/path/to/image.jpg';
$realImagePath = realpath($imagePath);

// Use $realImagePath when loading the image in your PHP application
