Today Google introduced Instant Previews, a new search feature that helps people find information faster by showing a visual preview of each result. This new feature of Google search results will provide a visual preview of a Web site that turns up in a search results listing before users click through to it. The goal is to help users quickly identify sites that aren’t relevant to what they want, based on a graphical image of the page selected as a search result.
Instant Previews is not live yet for everyone, but you can try it out by visiting this link. With Instant Previews enabled you will see a small magnifying glass next to the results.
Clicking on the magnifying glass will activate the feature and an image preview of the site will be loaded on the right. After this, hovering the mouse over another result will load the preview for it.
Instant Previews also works with the keyboard navigation shortcuts Google introduced recently. Pressing the right arrow key with a search result selected will activate Instant Previews. Pressing the left arrow key will deactivate it.









Why call them instant previews ? I used to have instant thumbnails beside my searchresults with this addon for firefox ( SearchPreview ): https://addons.mozilla.org/en-US/firefox/addon/189/ without clicking on some magnifying glass. The addon stopped working now….
