Note: This works with images on flickr.com only
fiveprime.org/blackmagic is a “magic” link on flickr.com – by adding this text:
<a href="http://fiveprime.org/blackmagic" rel="nofollow"> B l a c k M a g i c</a>
in any image comment, you will get a clickable link – as ususal. With one difference, this link is magic in the sense that it adapts to where it is – there is no need to specify more – the image that you commented will show up in the blackmagic browser (as you click on the link!).
BlackMagic also remembers how you were viewing images last time. Medium/Large, black or grey background; change your settings and they will be used next time.
As you see the image, there is a “More” link in the upper left corner.
A click displays a bunch of text (begins with “<a” and ends in “</a>”)…
This bunch can be copied into any place where “HTML” is accepted… The result is a “BlackMagic”-link to the image (including the current settings).
