Comment:

 Hi @Hube2,

 Thanks for the request. I may be misunderstanding, but it sounds like
 you're trying to implement the [https://usecases.responsiveimages.org
 /#art-direction art direction use case], which is where you would use
 different crops and/or aspect ratios at specific breakpoints, rather than
 different sizes of the same image. Is that correct?

 If so, then `srcset` and `sizes` attributes on an `<img>` element aren't
 really the right tool for the job. Instead, you'll want to use the
 `<picture>` element, where you can specify a set of sources at different
 breakpoints.

 It I'm misunderstanding, could you give an example of the markup you'd
 like to be able to produce?

 Thanks,
 Joe
