YITH WooCommerce Watermark (Premium Plugin):
It is a very well known fact. On the web, everyone can download images. They have complete freedom to reuse them without any permission. They can also edit them, even for not so legal or unethical purposes.
Today new technologies allow a not-controlled diffusion of images. Also, who takes them can do it really easily, even using the software. The software automatically grabs pictures from a site, stressing your server performances and your visibility.
With YITH WooCommerce Watermark, you will need a few clicks to apply a logo or a watermark on all your product images. This discourages spiteful people to grab them or use the malevolent software.
The plugin also lets you apply watermarks and regenerate all images. Also, the correct resolution is used in order to extremely reduce a long, boring and exhausting modification.
