What are potential pitfalls when using the PHP function img_write() for resizing images?

One potential pitfall when using the PHP function img_write() for resizing images is that it may not properly handle the aspect ratio of the original image, resulting in distorted or stretched images. To solve this issue, you can calculate the aspect ratio of the original image and adjust the resizing dimensions accordingly to maintain the correct proportions. 

// Calculate the aspect ratio of the original image
$original_width = imagesx($original_image);
$original_height = imagesy($original_image);
$aspect_ratio = $original_width / $original_height;

// Set the desired width and calculate the corresponding height
$desired_width = 300; // Set your desired width here
$desired_height = $desired_width / $aspect_ratio;

// Resize the image with the correct aspect ratio
$resized_image = imagecreatetruecolor($desired_width, $desired_height);
imagecopyresampled($resized_image, $original_image, 0, 0, 0, 0, $desired_width, $desired_height, $original_width, $original_height);

// Output the resized image
imagejpeg($resized_image, 'resized_image.jpg');
