Use image original size in Picture component

[rubenesque-code]

I'm wandering if there's a way to use the original size of images when using the Picture component?

As a workaround, I've set sizes to an empty string and set the width of each img to an empty string in a script.

Apologies if I've missed anything in the docs but I've had a good read.

p.s. I only really want to use the Picture component for the blur-in effect.
