What are some best practices for implementing branding on images in PHP?

To implement branding on images in PHP, one best practice is to use the GD library to overlay a watermark or logo onto the image. This can help protect your images from being used without permission and also helps to reinforce your brand identity. Additionally, you can add text overlays with your brand name or website URL for further branding. 

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

// Load the watermark image
$watermark = imagecreatefrompng('watermark.png');

// Get the dimensions of the original image and watermark
$originalWidth = imagesx($originalImage);
$originalHeight = imagesy($originalImage);
$watermarkWidth = imagesx($watermark);
$watermarkHeight = imagesy($watermark);

// Calculate the position to place the watermark
$positionX = $originalWidth - $watermarkWidth - 10;
$positionY = $originalHeight - $watermarkHeight - 10;

// Merge the watermark onto the original image
imagecopy($originalImage, $watermark, $positionX, $positionY, 0, 0, $watermarkWidth, $watermarkHeight);

// Output the final image with the watermark
header('Content-Type: image/jpeg');
imagejpeg($originalImage);

// Clean up memory
imagedestroy($originalImage);
imagedestroy($watermark);
