What potential issue could arise when using the createThumb function in a loop to generate thumbnails for multiple images?

One potential issue that could arise when using the createThumb function in a loop to generate thumbnails for multiple images is the excessive consumption of memory resources. This can happen if the function is not properly optimized to handle a large number of images simultaneously. To solve this issue, you can implement a mechanism to limit the number of images processed in each iteration of the loop, thus reducing the memory usage. 

// Limit the number of images processed in each iteration of the loop
$batchSize = 5;

// Loop through all images and generate thumbnails
$totalImages = count($images);
for ($i = 0; $i < $totalImages; $i += $batchSize) {
    $batchImages = array_slice($images, $i, $batchSize);
    
    foreach ($batchImages as $image) {
        createThumb($image);
    }
}
