srcset in Bootstrap 5 Lightbox

[Anwyen]

Hey there,
I'm building a page using bootstrap 5 and found your very nice js to add lightbox using BS5. Since I try to optimize my page concerning loading speed, I was wondering if it is possible, to make lightbox using srcset for optimal image sizes in different viewports.

Hope this question is not too stupid, since I'm quite new to coding webpages.

I hope for an answer.

Best regards,
Christoph
