Note: The "allow access to search results" has to enabled in order for the extension to work.
Once GooglePanicImages is enabled, a 'View' button is displayed on top of images from Google Image search, when images are hovered over. Clicking on 'View' opens the source image directly in a new tab.
The 'View' button is displayed at the regular search and details view of the Google Image search, as possible.
On detailed view the subimages selected will create on first click the "View" link, on second click the image is opened in the Google preview.
This works ouf of the box for the initial 100 images found - after that, in reason of a Google encoding for the URLs, you have to click on the image in order to get the "View" link.
