Has anyone ever encountered this?

I'm trying to render scenes created in Poser, in Blender, largely because I can add caustics but also because the lighting is more sophisticated and the support for stuff like grass is better. But this: this is annoying. Almost never does the actual xxx.png or xxx.jpg work: it's always the xxx.jpg.004 that does. And getting rid of the bogus references... a royal pain.

Does anyone know of a script or work-around? I spend seriously HOURS cleaning this nonsense up.
