As part of the 2013 site redesign, I've been forced to conclude that navboxes can no longer have pictures. I regret having to remove this feature, because I know precisely how much work has been involved in creating these specialised, 80px width pics.
However, as we added more and more columns to these navboxes (note how the more recent series of DW have more columns at {{DWTV}}), the mathematical formula behind the assignment of column widths could no longer work, in some browsers, in the fixed-width Wikia skin. Many of our navboxes were in fact wholly broken for a long time, but the white background kinda disguised the error. The dark blue background wasn't so forgiving. Ever since our new dark/light duality began, it's been screamingly obvious that something was wrong with the navboxes.
There are a number of possible fixes for the problem, but by far the simplest is just to remove the ability of the navboxes to accept pictures. So that's been done, and {{DWTV}}, {{DWN}} and others now have workable widths again, and I can proceed with actually styling the boxes so that they're legible in the dark skin.
Thanks to all who helped illustrate these navboxes up to this point. Your work was appreciated.
