BackTrack for Safari 2.5

Problem: We often come across images on the web devoid of any context. We would like to know the source of a picture, learn more about the subject or the circumstances in which the photo was created.
Solution: BackTrack for Safari harnesses the power of multiple search engines to find out where an image shows up on the web and possible keywords which may help you discover more about it.
How it Works:
When you find a picture or link you would like to search, right-click and select "BackTrack this Image" to get an overview of search engines. Choose "MultiSearch" to jump straight to searching.
You can also use the toolbar button or keyboard shortcut, it will try to detect a main image on the page to search.
