I've created two versions of logo, a vertical and a horizontal one, the first for mobile screens, the second for desktop, to swap from one to another I need picture element. Unfortunately I've failed to implement it both in Dreamweaver, and Sublime text editor. The only thing I've noticed after hours of research, is that it only works with dummy images (placehold.it). Even more the problem seems to be the srcset attribute (which fails to display anything, no matter what is the browser), in contrast with the src attribute which seems to display the source image correctly. Any kind of help would be most appreciated! (code follows)
<picture>
<source media="(min-width:600px)"
srcset="assets/desk/logo horiz.png"/>
<img src="assets/mob/logo vertical.png"/>
</picture>
