Image greyscale

Hey BetuwePC!

Please add following code to Quick CSS in Enfold theme options under General Styling tab

#main img { filter: grayscale(100%);
    -webkit-filter: grayscale(100%); 
-moz-filter: grayscale(100%); 
-o-filter: grayscale(100%); 
    filter: gray;
    -webkit-transition: all .6s ease;
transition: all .6s ease;
-moz-transition: all .6s ease;
-o-transition: all .6s ease; }

#main img:hover {    filter: grayscale(0%);
    -webkit-filter: grayscale(0%);
-moz-filter: grayscale(0%);
-o-filter: grayscale(0%);
    filter: none; }
.image-overlay { display: none !important; }

Cheers!
