How to make a watermark on product photos?

Question

Watermark

Recommend a plugin that will make a watermark on product photos in a woocommerce store.
I tried Product Watermark for WooCommerce but after turning it on, product pages stop loading (I use the latest flatsome template).
Manually making is not an option for several thousand goods.

htaccess rule with url saving and image processing on the fly:
And php itself:

$stamp = imagecreatefrompng('watermark.png');
$im = imagecreatefromstring(file_get_contents($_GET['img']));

$pc = imagesx($im) / 300;
$s_w = imagesx($stamp) * $pc;
$s_h = imagesy($stamp) * $pc;

$stamp_p = imagecreatetruecolor($s_w, $s_h);
imagealphablending($stamp_p, false);
imagesavealpha($stamp_p, true);
imagecopyresampled($stamp_p, $stamp, 0, 0, 0, 0, $s_w, $s_h, imagesx($stamp), imagesy($stamp));

$marge_right = 10;
$marge_bottom = 10;
$sx = imagesx($stamp_p);
$sy = imagesy($stamp_p);

imagecopy($im, $stamp_p, imagesx($im) - $sx - $marge_right, imagesy($im) - $sy - $marge_bottom, 0, 0, $sx, $sy);

header('Content-type: image/png');
imagepng($im);
imagedestroy($im);

You can batch apply a watermark to several thousand pictures: https://ez-catalog.ru/nalojenie-vodyanogo-znaka-v-...
