Google Image Relinker

This is a Greasemonkey Extension which improves google's image search results :

  • Removes the annoying frameset when you click the image thumbnail
  • Adds a link directly to the image

Version History

Edit

2.01

Edit

I started on verion 2.01, because this is a fork of the original Google Image Relinker written by Patrick Cavit, (http://patcavit.com) and Eric Hamiter( http://roachfiend.com/)

2.02

Edit

  • Added logging to Firebug.
  • Change from decodeURI to unescape. There are two ways that google could have encoded the urls, and I believe they use the "escape" way, not the "encodeURI" way.
