Search to have a static link.

[SickFinga]

Can't really sum it up in one sentence what I mean, but let me try to explain.

The idea is to have a search query in the link, like in this example
http://www.google.com/search?q=keyword

This way you can link to the pictures that share the same keyword, but not in the same album.

I'm using v 1.4.4. The tag cloud isn't included by default, but clickable links to keywords results is available as an admin option.
