Here's the way to do it inside Vue with an ordinary rightside-up Poser texture: In the Material Editor select Mapped Picture & load the image. In the Tiling section, select "Mirror Y". In the Picture File box you'll see the filename & dimensions (WxH) of the map, type the height of the picture into the Picture "Offset Y" box. What this does is creates alternating tiles (rightside-up and upside-down) and shoves the rightside-up tile upward so we can see it. If you're using texmaps for figures, I suggest flood filling the white background with a median skin tone to avoid white seams on the figure.
