[MediaWiki-l] Image thumbnailing in MediaWiki

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?
