Where to turn it on
On the gallery page, click Gallery settings. The switch is in the Protection section, with a short description. You'll find the same setting in the Watermark tab, in the When to apply group.

What it does
- the preview your client sees drops to 900 px on the long side,
- compression is stronger than usual,
- the watermark stays the same,
- your stored photos don't change, only the preview does.

What it won't do
It won't block screenshots or saving an image from the browser. It protects by making the saved file too weak to use for anything except viewing.
