Bug #: 30002
Summary: Inconsistent query behavior for images, and need
options for display of sized thumbnails and/or plain
links
Product: MediaWiki extensions
Version: any
Platform: All
OS/Version: All
Status: NEW
Severity: trivial
Priority: Unprioritized
Component: Semantic MediaWiki
AssignedTo: mar...@semantic-mediawiki.org
ReportedBy: fastgoldf...@gmail.com
CC: jeroen_ded...@yahoo.com
Classification: Unclassified
A query like this:
{{#ask: [[Category:Images]] | ?Caption | ?Modification date |
mainlabel=[[:Category:Images]] | limit=2}}
Normally produces a table of the image thumbnails. The only way I know of to
control the thumbnail size is by editing LocalSettings.php with something like
this:
$wgDefaultUserOptions['thumbsize'] = 0;
$wgThumbLimits = array(
60,
90,
120,
150,
180,
200,
250,
300
);
Where 0 on $wgDefaultUserOptions would produce a 60px default thumbnail size
for the entire wiki (not only the queries). Here's the relevant documentation
of those parameters:
http://www.mediawiki.org/wiki/Manual:$wgDefaultUserOptions
http://www.mediawiki.org/wiki/Manual:$wgThumbLimits
Note also that these are user options that only affect new users and existing
users that have not changed from the default. So, before this takes effect for
the entire system, maintenance must be done with userOptions.php in the
Mediawiki maintenance directory, as described here:
http://www.mediawiki.org/wiki/Manual:UserOptions.php
Obviously, that solution isn't going to work in practice, since people may have
good reasons to choose a different thumbnail size from the default (small
screen requiring smaller images, or poor vision, requiring larger ones).
In addition, the results obtained from image queries are sometimes thumbnails
(on most pages), and sometimes just links to the file page (on Special:Ask
"further results" pages, the semantic search page, and maybe others I don't
know about).
Semantic Mediawiki needs to provide query options to control whether a
thumbnail or a file page link is displayed. For thumbnails, an option needs to
be available to control the thumbnail size.
Right now, this can only be done by creating and then specifying a custom
template to use for the query.
That is OK for site developers in circumstances where the query is to be used
frequently, but it's too much for an ordinary user to be required to do in
casual queries, especially when using convenience features like Special:Ask and
Semantic Search.
