- Even after learning not to render all HTML with images at once, the implementation questions remain - Web Components for galleries that only fetch images when visible? HTMX?
It ended up being way more work than I anticipated!
The question is: Is it worth implementing this to save some bandwith? You could just serve 2x images directly instead and call it a day (3x is not much better, 2x is not much bigger than 1x).

I implemented responsive images for a backend CMS some time ago and they're still surprisingly tricky:
- Figuring out which sizes to transform your original images into is challenging
- The number of image variations explodes quickly (sizes × formats × container types × images per post × posts per page). On an image-heavy blog with lots of thumbnails, this unexpectedly led to 20k image rows being fetched from the database!
