What are the limitations of using PHP to manipulate and display images on a website?

One limitation of using PHP to manipulate and display images on a website is that it may not have all the advanced image processing capabilities as dedicated image processing libraries or software. To overcome this limitation, you can use PHP's GD library or ImageMagick extension to perform various image manipulation tasks such as resizing, cropping, and adding filters. 

// Example using GD library to resize an image
$sourceImage = imagecreatefromjpeg('source.jpg');
$width = imagesx($sourceImage);
$height = imagesy($sourceImage);
$newWidth = 200;
$newHeight = ($height / $width) * $newWidth;
$targetImage = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($targetImage, $sourceImage, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height);
header('Content-Type: image/jpeg');
imagejpeg($targetImage);
imagedestroy($sourceImage);
imagedestroy($targetImage);
