What are some potential issues when using imagecopy in PHP for including images in a script?

One potential issue when using imagecopy in PHP for including images in a script is that the image quality may be degraded if the images have different sizes or aspect ratios. To solve this issue, you can resize the images to have the same dimensions before using imagecopy. 

// Load the images
$image1 = imagecreatefromjpeg('image1.jpg');
$image2 = imagecreatefromjpeg('image2.jpg');

// Get the dimensions of the images
$width1 = imagesx($image1);
$height1 = imagesy($image1);
$width2 = imagesx($image2);
$height2 = imagesy($image2);

// Resize the images to have the same dimensions
$newImage1 = imagecreatetruecolor($width2, $height2);
imagecopyresampled($newImage1, $image1, 0, 0, 0, 0, $width2, $height2, $width1, $height1);

// Use imagecopy to combine the images
imagecopy($newImage1, $image2, 0, 0, 0, 0, $width2, $height2);

// Output the final image
header('Content-Type: image/jpeg');
imagejpeg($newImage1);

// Free up memory
imagedestroy($image1);
imagedestroy($image2);
imagedestroy($newImage1);
