Gallery Hotspot Icon

Hey schenkco!

Please turn on custom CSS field for ALB elements – http://kriesi.at/documentation/enfold/turn-on-custom-css-field-for-all-alb-elements/ and edit your element and give it a custom CSS class and then add following code to Quick CSS in Enfold theme options under General Styling tab

.your-custom-class .av-image-hotspot_inner {
    background: url(https://kriesi.at/wp-content/themes/kriesi/images/logo.png)!important;
    background-repeat: no-repeat!important;
    background-size: contain!important;
    background-position: 50% 50%!important;
}

Cheers!
