Problem with fullscreen and picture tag's Avatar

18 Oct, 2020 10:31 PM


I could almost cover all my needs with the plugin. However, I am using picture tags for the slider. For example:

<source srcset="img.webp" type="image/webp">
<source srcset="img.jpg" type="image/jpeg">
<img class="rsImg" data-rsBigImg="img-big.jpg" src="img.jpg">

So Chrome gets the webp version of the picture, other browsers with non webp support the normal jpg. However, when I switch to Fullscreen, Chrome still shows me the small webp Version, since the plugin only changes the <img> src.

Is there already a solutions, how to deal with such a layout? I cant think of a solutions right now, the srcset should be changed too? Anyway, maybe there is someone who solved this problem.

Best Regards

    You'll need to remove rsImg class entirely and implement your own source switching, you may use events like:

    var slider = $('.royalSlider').data('royalSlider');
    slider.ev.on('rsEnterFullscreen', function() {
    slider.ev.on('rsExitFullscreen', function() {

    for example, to access img element of each slide:

    $.each(slider.slides, function(i, slide) {
      slide.content[0].querySelector('img').src = ...

    You may either switch src directly, or set different srcset/media while in fullscreen.
