Are there any potential compatibility issues or differences in behavior of the getimagesize function in PHP that could explain why it works on a test page but not for a specific user?

The issue may be related to the file path or permissions for the specific user. Ensure that the file path is correct and accessible to the user running the script. Additionally, check the file permissions to ensure that the user has the necessary rights to read the file. 

<?php
// File path to image
$image_path = 'path/to/image.jpg';

// Check if file exists and is readable
if (file_exists($image_path) && is_readable($image_path)) {
    // Get image size
    $image_size = getimagesize($image_path);
    
    // Output image width and height
    if ($image_size) {
        echo 'Image width: ' . $image_size[0] . 'px<br>';
        echo 'Image height: ' . $image_size[1] . 'px';
    } else {
        echo 'Unable to get image size.';
    }
} else {
    echo 'Image not found or not readable.';
}
?>
