What potential issues or errors could arise when exporting multiple images using the provided PHP code?

One potential issue that could arise when exporting multiple images using the provided PHP code is that the script may run out of memory if there are a large number of images being processed simultaneously. To solve this issue, you can free up memory by unsetting the image resources after each iteration. 

// Export multiple images
$images = ['image1.jpg', 'image2.jpg', 'image3.jpg'];

foreach ($images as $image) {
    $source = imagecreatefromjpeg($image);
    
    // Image processing code here
    
    // Free up memory by unsetting the image resource
    imagedestroy($source);
}
