I want to skip the first in the .map function what I do now is this:

block.gallery.map((item, i) => (

       <div className=gallery-item key={i}>

        { block.gallery.length > 4 && i !== 0 ?

          <div className=inner>

             <img src={block.gallery[i].images.thumbnail_sm} alt={block.title} srcSet={`${block.gallery[i].images.thumbnail_md} 1x, ${block.gallery[i].images.thumbnail_lg} 2x`} className=img-fluid title= />

             <div className=img-overlay>

               <span className=img-overlay-body>{ block.gallery.length - 4 }+ <span className=hidden-xs>Foto's</span></span>

             </div>

           </div>

           :

           <img src=http://placehold.it/800x538 alt= className=img-fluid title= />

          }
