Dear MediaWiki experts,
I cannot really figure out the behaviour of MediaWiki regarding thumbnailing. What I want
to achieve is that my MediaWiki installation produces thumbnails in a specified size.
What I did after reading through several help pages is this:
---------------------------
# Images und Thumbnails
$wgThumbLimits = array( 80, 250, 390 );
$wgDefaultUserOptions['thumbsize'] = 1; // thumb size 250
$wgImageLimits = array( array( 80, 90 ), array( 800, 600 ), array( 1280, 1024 ) );
$wgDefaultUserOptions['imagesize'] = 2; // image size 800, 600
---------------------------
In my opinion this should guarantee that for every image uploaded, there is an 80, 250 and
390px sized thumbnail. In many cases this is true, but there are some cases were I can
find a 100px thumbnail, but no 80px thumbnail.
If I understand it correctly, this can perfectly be the case if any user sets his/her
preference to 100px. I don't mind so much extra sizes to be produced, but I want to
make sure that a 80px thumbnail is there.
Maybe in the cases where it is not present the images were uploaded before the above
mentioned setting was made? But how can I get the wiki to redo thumbnails in my desired
size?
cheers,
Bernhard
