What are the potential memory limitations when using PHP to manipulate and save images?

When manipulating and saving images in PHP, one potential memory limitation is running out of memory due to large image sizes or processing multiple images at once. To solve this issue, you can free up memory by using functions like `imagedestroy()` to release the memory allocated for images after you are done manipulating them. 

// Load an image
$image = imagecreatefromjpeg('example.jpg');

// Manipulate the image here

// Save the image
imagejpeg($image, 'output.jpg');

// Free up memory
imagedestroy($image);
