update 2

i examined html generated , doesn't appear off original:

generated suggestion:

<a class="thumbnail fancybox" data-rel="gallery" title="project three" href="/image.creative%2fmain%2fimg18.jpg">     <img class="full-width img-responsive" src="/assets/creative/main/img18-972c688b1a840ae0a8ec9b22012ae6c4aa69ca6894da2029277fa2c163b41fc0.jpg" alt="img18" />     <span class="rounded-x portfolio-box-in">        <i class="icon-magnifier-add"></i>     </span> </a>

here original html working code:

<a href="assets/img/main/img18.jpg" title="project three" data-rel="gallery" class="thumbnail fancybox">         <img alt="" src="assets/img/main/img18.jpg" class="full-width img-responsive">         <span class="portfolio-box-in rounded-x">            <i class="r icon-magnifier-add"></i>         </span>     </a>

this not tested code, can try once:

<%= link_to image_path("creative/main/img18.jpg"), class: "thumbnail fancybox", data: { rel: "gallery" }, title: "project three"  %>  <%= image_tag "creative/main/img18.jpg", class: "full-width img-responsive" %>  <span class="rounded-x portfolio-box-in">    <i class="icon-magnifier-add"></i>  </span> <% end %>
