Link Original Image - (c) 2005-2009 Johannes la Poutre
Greasemonkey User Script; looks for thumbnail images from Flickr.
Links these images to their original uploaded (full size)
versions. This also works for any page where thumbnails are
displayed directly from the Flickr servers.
The script adds an icon on top of thumbnail images.
Clicking this icon takes you to the original original
uploaded photo version.
On March 1, 2007, flickr started to use a different naming
scheme for different image sizes. The work around is to
fetch the "zoom page" (the "all sizes" link with magnifying
glass) and extract the link to the original image from there.
Some users don't allow links to high resolutions from the
zoom page, in this case no "ORIG" icon will be displayed.
