When I want to search for images, the first place to look for that comes to my mind is Google Image Search. It does lack a few features, but I still use it for all my image-searching needs.
To get a direct link for any image in Google Image Search, you have to first click the image and get the direct link from the website page where that image belongs to...
But thanks to a Greasemonkey script, getting a direct link is much easier now.
Google Direct Image Links is a Greasemonkey script that adds a link to the direct URL of the image above every search result in Google Image Search.
This is a very useful script for people (like me) who use Google Image Search very often. No need to open the image page first just to get the direct link. You can copy it directly from the results page.
Download the script from the link given below.
