    Refer to https://helpx.adobe.com/experience-manager/using/graniteAPI.html and https://helpx.adobe.com/experience-manager/6-3/sites/developing/using/reference-materials/diff-previous/changes/com.day.cq.dam.api.AssetManager.html

    or do something like this

    final Iterator<Resource> assets = findAssets(resourceResolver, "YOUR CUSTOM DAM PATH");

      while (assets.hasNext()) {

      final Asset asset = assets.next().adaptTo(Asset.class);

     

      }

      Asset asset = resource.adaptTo(Asset.class);

      String fileName = asset.getMetadataValue("dc:title");

      if (fileName instanceof Object[]) {

      Object[] titleArray = (Object[]) asset.getMetadata("dc:title");

      fileName = (titleArray.length > 0) ? titleArray[0].toString() : "";

      } else {

      fileName = asset.getName();

      }

      Property property = asset.adaptTo(Node.class).getNode(JcrConstants.JCR_CONTENT + "/renditions/original/" + JcrConstants.JCR_CONTENT).getProperty(JcrConstants.JCR_DATA);

      fileSize = property.getBinary().getSize();

      String thumbnailPath = asset.adaptTo(Node.class).getNode(JcrConstants.JCR_CONTENT + "/renditions/" + "you/rendition/to/use").getPath();
