This variable influences how intermediate thumbnails are used when $wgThumbnailBuckets is enabled: an intermediate will only be selected as the source for creating the target thumbnail if it is at least $wgThumbnailMinimumBucketDistance pixels wider. For example, with the following buckets:

$wgThumbnailBuckets = array ( 128, 256, 512 );

and a distance of 50:

$wgThumbnailMinimumBucketDistance = 50;

if we want to render a thumbnail of width 220px, the 512px bucket will be used, because 220 + 50 = 270 and the closest bucket bigger than 270px is 512.
