Are there specific considerations to keep in mind when working with image manipulation functions in PHP, such as imagecreatefromjpeg and imagecopy?

When working with image manipulation functions in PHP, it is important to ensure that you are handling image resources properly to prevent memory leaks. Make sure to free up memory after working with images by using functions like imagedestroy. Additionally, always check that the image files exist and are valid before performing any operations on them.

// Example code snippet demonstrating proper handling of image resources in PHP

// Load a JPEG image
$image = imagecreatefromjpeg('image.jpg');

// Check if the image resource was created successfully
if ($image) {
    // Perform image manipulation operations here

    // Free up memory by destroying the image resource
    imagedestroy($image);
} else {
    echo 'Error loading image file';
}
