What are common issues when retrieving image information using PHP?

One common issue when retrieving image information using PHP is not properly handling errors that may occur during the process, such as file not found or unsupported file types. To solve this, you can use error handling techniques like try-catch blocks to catch and handle any exceptions that may arise. 

try {
    $imageInfo = getimagesize('image.jpg');
    if($imageInfo !== false) {
        echo 'Image type: ' . $imageInfo['mime'];
        echo 'Image width: ' . $imageInfo[0];
        echo 'Image height: ' . $imageInfo[1];
    } else {
        throw new Exception('Unable to retrieve image information.');
    }
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
