Google has launched a few new updates to its images searches in the past 48 hours designed to help users find images quicker from the main search area of the Google site.
Many of the features Google introduced to its images specific search a little while back, have now been rolled out into its main search results. Images within a search now appear in a tiled layout, with hover previews providing you with a larger thumbnail together with more information about a particular image.
Also if Google detects you are looking for images it will expand your search to include more images related to your search term. For example:
If you add words like “photos”, “pictures”, and “images” to a query, that means you’re probably not looking for a blog post or video. In a search for [nebula pictures], instead of just three or four pictures at the top of the results, now you’ll find more than a dozen beautiful pictures filling up most of the page. (as above)
