Do I need to duplicate path to default image img/myphoto.jpg in source tag when using picture tag, or I can leave it fallback by itself to that if picture tag is not supported? (less code)
This:
<picture>
<source srcset="img/myphoto.webp" type="image/webp">
<source srcset="img/myphoto.jpg" type="image/jpeg">
<img src="img/myphoto.jpg" alt="">
</picture>
or this:
<picture>
<source srcset="img/myphoto.webp" type="image/webp">
<img src="img/myphoto.jpg" alt="">
</picture>
