Watermark Everything

Web publishers use a lot of tactics to prevent you from downloading their images: transparent image overlays, non-viewable source code, etc. — but they all suck. You can circumvent almost any of them with your browser’s built-in developer tools.

If you want to discourage unauthorized downloading — which is all you can really do — I suggest a low-tech approach: watermarking.

For example, let’s say I want to mark my vacation photos from Venice. I’m going to use WaterMarker, a Python CLI written by Jasim Muhammed. First, a text mark:

```bash ./watermarker ~/i.jpg ~/o –wm-text ‘[email protected]’ –wm-text-font ‘Comic Sans MS’ –wm-position ‘TOP_CENTER’


WaterMarker - text

Ugly, but effective. Next, I’ll overlay an image (of my beautiful face) and convert the output to PNG:

bash ./watermarker ~/i.jpg ~/o --wm-image ~/wm.png --output-format png --wm-position 'BOTTOM_CENTER'

WaterMarker - image

Neat, right? And since WaterMarker has flags for resizing and bulk processing, I can watermark all of my vacation photos with a single terminal command.
