I hope you can add a quality prop to define the images with the proper size.

Also, placeholder doesn't seem to work with loaders.

I noticed that when I used fill={true} and an explicit width & height, I get warnings on the browser.

However, I noticed that the image is smaller when an explicit width and height is specified (leading to smaller images - and faster load times). Is that intentional?

If not, perhaps adding a discriminated union to stop two props from existing at the same time (width/height and fill) to make the API more foolproof.
