Google unveils search by image. Drag & Drop, upload, copy & paste URLs, or use extensions.
According to Google:
“Whether you type, speak or upload a photo, once you’ve indicated what you’re looking for the next step in your search is to sift through the results and pick one. To make this faster, last year we introduced Google Instant, which gives you search results while you type. We estimated Google Instant saves you between two and five seconds on typical searches. But once you’ve picked a result, you click, and then wait again for the page to load—for an average of about five seconds.
We want to help you save some of that time as well, so today we took the next step for Google Instant: Instant Pages. Instant Pages can get the top search result ready in the background while you’re choosing which link to click, saving you yet another two to five seconds on typical searches. Let’s say you’re searching for information about the Smithsonian Folklife Festival, so you search for [dc folklife festival]. As you scan the results deciding which one to choose, Google is already prerendering the top search result for you. That way when you click, the page loads instantly.”
