Images in opensearch results - Mediawiki-api

23 Apr 2010

As an example:
The following query:
http://en.wikipedia.org/w/api.php?action=opensearch&search=Berlin&f…
returns 10 results, one of them:
<Item>
	<Text xml:space="preserve">Berlin S-Bahn</Text>
	<Description xml:space="preserve">The Berlin S-Bahn is a rapid transit
system operated by S-Bahn Berlin GmbH, a subsidiary of the Deutsche Bahn.
</Description>
	<Url
xml:space="preserve">http://en.wikipedia.org/wiki/Berlin_S-Bah…
	<Image
source="http://upload.wikimedia.org/wikipedia/commons/thumb/e/e7/S-Bah…
width="50" height="50" />
</Item>

has the aforementioned image tag. 
...
  I'm
 guessing whatever's showing you these images is using some heuristic
 like finding the first image on the page and showing you that. 
I think so as well. I can confirm though that it is not always returning the first image
on a page. Furthermore there are some pages with images, that do not return image tags in
the corresponding opensearch result.

I would be interested in taking a look at the code that is generating the image tags in
the opensearch results, but I have absolutly no idea where I should search for the code.

  Hi
 Hope I  am posting to the correct list.

 I am doing an opensearch query via the api
(http://en.wikipedia.org/w/api.php?action=opensearch&search=Te)=Te). Some search results
come with a tiny thumbnail image link. I would like to know if the thumbnails are defined
when someone is creating a wikipedia page or if there is some kind of algorithm that
automatically creates these thumbnails. Would be glad about any information about this
matter.
  The opensearch result itself just contains page titles, no images. I'm
 guessing whatever's showing you these images is using some heuristic
 like finding the first image on the page and showing you that.
