In 2013 Google added a cool feature that allowed you to find your photos directly from Google Search. You could search for [my photos], [my photos of beaches], [my photos from New York], [my photos from 2011] and many other similar queries.
At that time, Google displayed small thumbnails for some of the search results. It looks like Google has updated the photos card and now shows a lot more photos, bigger thumbnails and it also includes some information about the photos (date, location). For some of my queries, Google displayed more than 100 results.
Google shows the search results from Google+ Photos and individual links send you to the Google+ Photos pages, but the link below the search results is for Google Photos. For some searches, Google Photos returns fewer results, since it doesn’t include images from Blogger and photo spheres.
