Regarding using <picture>

I'm using <picture>. Just wondering; should you always support retina displays by providing higher quality/dimension images? or is the main focus to change images when a breakpoint occurs?

Eg of different images for different breakpoints;

<picture>

<source media="(orientation:landscape)" srcset="img/firstlook.jpg" />

<source srcset="firstlook-smallerscreen.jpg" />

<img class="content-image" src="firstlook.jpg" alt="First look - soft,simple new styles are here.">

</picture>

breakpoints are tricky. I would say both if possible, if you are trying to reach many device sizes by using lots of break points, I would try sourcing images of a medium to smaller size that you know sport good enough resolution that they can be seen clearly from a larger screen even though they won't be extremely high in quality. That way they will still appear properly saturated on the smaller screens

I agree with Luther. You are weighing up a bunch of factors. In general you want smaller file weights (file download size) on mobile connections, but it's these devices that are more likely to have high density screens. I have found that using bigger (dimensions) images at lower quality often has the desired result. If you work with a designer you'll find that matching the proportions of an image for different breakpoints become important too.
