There's no easy option for this, mainly because I can't think why you'd want to do this.
You could try looking at the "purge" option which allows you to delete cached thumbnails based on a pattern, eg. "texturecache.py purge all 'http://thetvdb.com/banners/actors'" would delete the matching thumbnails, most likely actors. If your fanart is named with a specific pattern, eg. "*-fanart.jpg" then you could delete them all with purge.
Or just delete the entire cache (deleting both Textures13.db and the Thumbnails folder), then re-cache only posters (texturecache.py c @cache.artwork=posters).
Though I'd expect these items to automatically come back into your cache unless you remove the artwork from your media library. In which case case clearing them out of the cache becomes a whole lot easier.
