Flickr Extension

From S23Wiki

This is a little Mediawiki Extension to include Flickr thumbnails. This example gets the X most interesting pictures (yes, Flickr really sorts like "sort"=>"interestingness-desc", by the users rating) for the tag you specify. You can use this to instantly put some related pictures on Wiki pages that dont have pictures yet. This is just a quick example, and can be heavily extended. Feel free to do so.


What you type:

<flickr limit=5>Fnord</flickr>


What you get:

The 5 most interesting photos from Flickr for the tag 'Fnord'
rositaNixie, skidoofnordWhy Do the Illuminati Always Get Their Walkway Shoveled First?102, hail eris.

If you wish to just insert one photo, of your choice, then you require this Flickr extension : http://wiki.edsimpson.co.uk/index.php/Flickr_Extension (which requires no additional PEAR or phpFlickr libraries).

The <flickr>-tag surrounds a keyword/Flickr Tag and optionally you can use limit to change the amount of thumbnails being shown, the maximum for tag-length is 255 chars and the maximum for limit is 10.

This is possible due to using a) the Flickr API, b) phpFlickr, c) the Debian PHP-Pear packages and d) a nice article in the latest iX (german) magazine, issue July 2006, p. 62 called "Bildergeflimmer". We could call this a Flickr->Mediawiki Mashup (->same iX issue, p. 55). Mutante 20:56, 18 June 2006 (CEST)
