Flickr updates every-so-often. disabling most previous Greasemonkey scripts.

But this one works well, as described, as of November 19th 2011.

The best GM scripts are direct to the point. This script does what it says.

It shows direct links to all image sizes, inline.

In Usability, inlining features strategically will let you access features easily will less mouse clicks.

From everything I have seen, this script does the perfect job of giving you the sizes and saving you a couple of mouse clicks.

Other scripts automatically give you large pics, granted, but this one automatically gives you an option of all of the sizes without much of a wait at all.
