"React does not recognize the `toString` prop [...]" warning

[EmilEriksen]

I'm using the <img {...responsiveImage} /> shorthand syntax. I just recently noticed the warning although I'm not sure when it started occurring. Not sure anything can be done about it. I should note that I'm using next-optimized-images but as far as I can tell the issue stems from this loader.

Thank you for developing this fantastic project!
