What are potential reasons for a PHP script to save images in lower resolution than the maximum supported by the camera?

Potential reasons for a PHP script to save images in lower resolution than the maximum supported by the camera could include the need to reduce file size for faster loading times on a website, conserve storage space, or optimize image quality for specific display purposes. To solve this issue, you can use PHP's image processing libraries to resize and compress images before saving them to the server. 

// Load the original image
$originalImage = imagecreatefromjpeg('original.jpg');

// Get the original image dimensions
$originalWidth = imagesx($originalImage);
$originalHeight = imagesy($originalImage);

// Set the desired maximum width and height for the resized image
$maxWidth = 800;
$maxHeight = 600;

// Calculate the new dimensions while maintaining aspect ratio
if ($originalWidth > $maxWidth || $originalHeight > $maxHeight) {
    $ratio = min($maxWidth / $originalWidth, $maxHeight / $originalHeight);
    $newWidth = $originalWidth * $ratio;
    $newHeight = $originalHeight * $ratio;
} else {
    $newWidth = $originalWidth;
    $newHeight = $originalHeight;
}

// Create a new image with the resized dimensions
$resizedImage = imagecreatetruecolor($newWidth, $newHeight);

// Resize and copy the original image to the new image
imagecopyresampled($resizedImage, $originalImage, 0, 0, 0, 0, $newWidth, $newHeight, $originalWidth, $originalHeight);

// Save the resized image as a new file
imagejpeg($resizedImage, 'resized.jpg');

// Free up memory
imagedestroy($originalImage);
imagedestroy($resizedImage);
