Pro Tips
- White or light gray text with 40-50% opacity works well on most images without obscuring content
- For image watermarks, use a PNG with transparent background for clean overlay
- Place watermarks in corners to minimize interference with the main image content
- Consider using your website URL as the text — it promotes your brand even if the image is shared
