Hmm so it generates

```
<img 
  src="//xxx/optimized/3X/2/2/guid_1_521x500.png" 
  alt="image" 
  width="521" 
  height="500" 
  srcset="//xxx/optimized/3X/2/2/guid_1_521x500.png, 
          //xxx/optimized/3X/2/2/guid_1_781x750.png 1.5x, 
          //xxx/optimized/3X/2/2/guid_1_1042x1000.png 2.0x"
>

```

I noticed the srcset URLs in the output sometimes start with `//` and sometimes `https://` .. is that intentional?

It looks like you can use `2x` instead of `2.0x` to save two bytes there, [per the documentation on srcset](https://developer.mozilla.org/en-US/docs/Learn/HTML/Multimedia_and_embedding/Responsive_images).
