Recently, web, allows users to create, organize, and search for images and other information sources through social tagging and other method activities. One of the image social bookmarking is such as Flickr. This research examines to increase the efficiency of image search result by creating indexes. The assumption of the experiment is a combination of social tagging and other factor such as image description that can improve web performance. Therefore, three indexers were created and were compared with the search results between a search engine using the indexing method of "Description with Tag" or DT indexer, "Posted Time With Tag" or PT indexer and the "Tag only" or T indexer which is a native method. The retrieval performance of this search engine is evaluated using the mean values of Normalized Discount Cumulative Gain (NDCG). The result illustrates that the search engine with indexer using DT indexer provides better indexer using the T indexer in all the ranks. This primary evaluation in the experiments proves that the chosen heuristic indexer can improve the efficiency of the web image searching on social bookmarking websites.}, }
