It makes no difference for me (one of the programmers), but might not help other users ;) Sorry, though, for my late answer. There is a configuration parameter $wgMaxImageArea, that limits the size of images that thumbnails are created from. This is set to 3500 x 3500 px as a standard. You might try to increase this. (see Manual:$wgMaxImageArea)
