This extension re-implements "View Image" button back to Google Images. The extension works on both desktop and mobile version of the Google Images website. Also, it supports all localized Google Images websites as well.
In comparison to the other similar add-ons, this one has the following advantages:
1. It uses non-persistent background script
2. There is no mutation observer in the code which potentially reduces the page loading.
3. It supports mobile view
4. It detects the right image even when the user slides an image back or forward.
