YITH WooCommerce Watermark

What the plugin does
Apply watermarks (logo, credits, copyright, etc.) to your WooCommerce product images to protect them.
How you can benefit from it:
apply your logo or a custom image to all the product images. Choose the position, size, and opacity to make it transparent or repeat the watermark throughout the whole image;
enter a custom text to use as a watermark and customize the font, color, and position;
keep your images safe from unauthorized use (this is especially useful if you sell digital products or if you want to keep copyright safe for images you publish online such as photos, pictures, comic strips, etc.);
highlight your brand on your images and attract new potential customers.
