So here is a question --

Is it permissible to use a thumbnail produced from a bowlderized version of a render? Suppose I had a NCGIABSWAS (Naked Catgirl in a Book Store with a Sturgeon), and I rendered a version where she was wearing clothes. Could I use the clothed version for the thumbnail? I understand that normally the thumb is supposed to come from the same render as the picture, but this might provide a reasonable accomadation, at least in those cases where it would be hard to produce a representative thumbnail without including incidental nudity.
