No surprise here. Just like the regular old text-based Google, Google Images is excellent when it comes to locating a lot of photographs and other types of pictures online:

The hands-down-best picture search experience with a complete collection of possibilities, plus the most exceptional ways (loads of filters and a powerful interface) to allow you to find them.

It also has an advanced (via settings) option for assisting you in getting specific. 

And it offers amazing reverse image search functionality: you can paste in a picture from a Dropbox folder, the phone’s camera roll, or Google Drive and search for similar pictures.

What’s The Image Search Engine?

Google’s Image Search Engine, also recognized as Google Images, is the search engine that is utilized for searching pictures online.

How Can You Access Google Images?

There are three methods of accessing Google Images:

  • Do a query in the web search and choose images from the menu.
  • Make use of the direct URL
  • On, choose Images from the top right corner

What Does The Image Search Engine Actually Do?

The image search engine is a part of the photo search system that crawls and indexes pictures, gets search queries for pictures, ranks photos, and returns results in response to the picture query.

What’s The Difference Between Google Image Search And Google Search?

The difference between Google’s Image Search Engine and Web Search Engine lies in the way the data retrieval is actually made for serving results to the user query.

Google’s Web Search Engine looks for numerous types of text-based docs across the internet and supplements the results utilizing alternate proprietary search engines like the image search engine.

Google’s Image Search Engine looks for media-matching queries, making it more reliant on metadata, filenames, and other text associated with pictures.

How Does The Google Image Search Engine Algorithm Actually Work?

It’s, in a manner, more simplistic than the web search as it includes fewer moving parts, but it can also be more compound as it needs a lot of processing power for returning the relevant media to the queries without any text-based content.

The core of the photo search engine algorithm depends on matching different search queries to the text associated with pictures.

Example of the text associated with pictures (states collected from several patents):

  • Image Caption
  • Anchor text of hyperlinks to the picture
  • Text from the page that the photo links to
  • Text from the page in which the picture was linked from
  • Photo metadata like the EXIF metadata
  • Filename

Once the first ranking of the photo search results is made, the top pictures are reprocessed to offer more relevant picture results.

In that reprocessing, pictures that are the most similar to all the other pictures in the subset are provided more relevancy, and pictures that are too diverse are re-ranked lower or even deleted.

The extra element can come in to make the search results more relevant, like:

  • Deleting or giving more weight to pictures with particular objects or landmarks based on the probability that the query is intended to
  • Deleting or giving more weight to pictures with faces is based on the probability that the query is actually intended to locate an individual’s picture.
  • Giving more weight to higher-quality pictures
