Hello, @ismailgorunmek,
Yes, you can add your logo with low opacity to the products in your WooCommerce store to prevent others from using or sharing them easily. This can be done by overlaying your logo on the product images or creating watermarked images. Here are the steps you can follow to do this in WooCommerce:
1. Manually Adding Watermark to Product Images
2. Automatically Watermark Images Using a Plugin (You can google and try with any third party plugin that better suits your requirements.
3. You can try with some Custom Code as well.
Best Regards,
PThemes Team.
