Are there any specific PHP functions or libraries recommended for handling image directories?

When handling image directories in PHP, it's recommended to use the `scandir()` function to get a list of files in a directory, and then filter out only the image files using functions like `pathinfo()` or `exif_imagetype()`. Additionally, the `glob()` function can be useful for retrieving files that match a specific pattern, such as only image files. 

// Get a list of files in a directory
$files = scandir('/path/to/directory');

// Filter out only image files
$imageFiles = array_filter($files, function($file) {
    $extension = pathinfo($file, PATHINFO_EXTENSION);
    $imageTypes = [IMAGETYPE_JPEG, IMAGETYPE_PNG, IMAGETYPE_GIF];
    return in_array(exif_imagetype($file), $imageTypes);
});

// Alternatively, use glob to get only image files
$imageFiles = glob('/path/to/directory/*.jpg');

// Loop through the image files
foreach ($imageFiles as $image) {
    // Process each image file
}
