    Flickr Extension

    Revision as of 10:30, 21 June 2006 by imported>mutante (→‎Source)

    I have written this little Mediawiki Extension to include Flickr thumbnails. This first 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 put some related pictures on Wiki pages that dont have pictures yet very quickly.

    What you type:

    <flickr>Leary</flickr>


    What you get:

    <flickr>Leary</flickr>

    What you type:

    <flickr limit=5>Fnord</flickr>


    What you get:

    <flickr limit=5>Fnord</flickr>

    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)

    As always, this is just a quick example, and can be heavily extended. Feel free to do so.
