I wish to have my VS2015 site display a more horizontal image I have created when on a desktop and a more vertical one on a mobile device. I have two separate cropped images to avoid distortion of sizing. I have tried using css with media queries to hide or show but it always showed both images (other media queries for resizing on the page work fine). I have tried the picture tag:
<picture>
<source srcset="../Images/Chalkboard414.jpg" media="(max-width: 450px)">
<source srcset="../Images/Chalkboard900.jpg">
<img srcset="../Images/Chalkboard900.jpg>"
</picture>
and downloaded picture fill and added this to header
Still no success. Sorry for the newbie question but I would love some help with what seems like a simple idea.
