You will need to install two items to get started. Opera can install Chrome extensions directly but first you must have Install Chrome Extensions.
After installing Chrome Extensions first, you'll be able to visit the Chrome web store to install the free TinEye browser extension.
Right-click on any web image and select Search Image on TinEye from the context menu. Results are displayed for you at tineye.com.
You can choose whether TinEye.com opens in the current tab, in a new tab in the foreground or in a new tab in the background and select the order in which your results will be returned (Last Used, Best Match, Most Changed, Biggest Image, Newest, or Oldest).
To set extension preferences select Show Extensions from the View menu. On the Extensions page, find the entry for TinEye Reverse Image Search and click on the Options button.
