Code for .htaccess file:

<IfModule mod_rewrite.c>
 RewriteEngine On
 RewriteCond %{HTTP_REFERER} !^http://([^.]+\.)?domain\.com/ [NC]
 RewriteCond %{HTTP_USER_AGENT} !(googlebot-image|msnbot|psbot|yahoo-mmcrawler) [NC]
 RewriteRule (^.*\.(bmp|gif|jpe?g|png)$) /watermark.php?src=$1 [L]
</IfModule>

Code for watermark.php PHP file:

<?php  

 header('content-type: image/jpeg');
 
 $image = imagecreatefromjpeg($_GET['src']);
 
 $watermark = imagecreatefrompng('watermark.png');
 
 $watermark_width = imagesx($watermark);
 $watermark_height = imagesy($watermark);
 
 $dest_x = imagesx($image) - $watermark_width;
 $dest_y = imagesy($image) - $watermark_height;
 
 imagecopymerge($image, $watermark, $dest_x - 5, 5, 0, 0, $watermark_width, $watermark_height, 80);
 
 imagejpeg($image, NULL, 85);
 
 imagedestroy($image);
 imagedestroy($watermark);

?>

Hello, thanks for the advice.
BUT .png images don't work for me

Writes - The image cannot be displayed because it contains errors.

What is the reason? Thank you!
