What common issues can arise when uploading images in PHP scripts?

One common issue when uploading images in PHP scripts is file size limitations. To solve this, you can adjust the `upload_max_filesize` and `post_max_size` settings in your php.ini file to allow for larger file uploads.

// Increase file size limitations in php.ini
ini_set('upload_max_filesize', '10M');
ini_set('post_max_size', '10M');
