Dear support,
Is it possible to load the same picture only once if we use the same image for more slides at https://napocatku.cz
The source code
<div id="slider" class="nivoSlider">
<img src="https://napocatku.cz/wp-content/uploads/2019/04/heading_1000-min.jpg" alt="" title="#slidecaption1" style="width: 1905px; visibility: hidden;"><img src="https://napocatku.cz/wp-content/uploads/2019/04/heading_1000-min.jpg" alt="" title="#slidecaption2" style="width: 1905px; visibility: hidden;"><img src="https://napocatku.cz/wp-content/uploads/2019/04/heading_1000-min.jpg" alt="" title="#slidecaption3" style="width: 1905px; visibility: hidden;"> <img class="nivo-main-image" src="https://napocatku.cz/wp-content/uploads/2019/04/heading_1000-min.jpg" style="display: inline; height: 1387px; width: 1905px;"><div class="nivo-caption">
shows that the same image three times. If I do not select the image, the slide is not displayed. I would like to reduce the size of the whole page because it seems the image is loaded 3x times?
