What potential issue can arise when using the getimagesize function in PHP and how can it be resolved?

The potential issue that can arise when using the getimagesize function in PHP is that it may not work properly with remote images due to restrictions on the server. To resolve this, you can use cURL to download the image locally before using getimagesize on it. 

$url = 'https://example.com/image.jpg';
$localImage = 'image.jpg';

$ch = curl_init($url);
$fp = fopen($localImage, 'wb');

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

curl_exec($ch);
curl_close($ch);
fclose($fp);

$imageInfo = getimagesize($localImage);

// Now you can use $imageInfo for further processing
