Are there any potential performance issues to be aware of when altering graphics in PHP?

One potential performance issue to be aware of when altering graphics in PHP is the use of inefficient image processing functions or algorithms, which can slow down the execution of your script. To mitigate this, consider using more optimized image processing libraries like GD or Imagick, and avoid unnecessary image manipulations. 

// Example of using GD library for image manipulation
$image = imagecreatefromjpeg('image.jpg');
$width = imagesx($image);
$height = imagesy($image);

// Resize image
$newWidth = 200;
$newHeight = ($height / $width) * $newWidth;
$newImage = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($newImage, $image, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);

// Save or output the modified image
imagejpeg($newImage, 'new_image.jpg');
imagedestroy($image);
imagedestroy($newImage);
