Texturing & Render problems

We had some major texturing problems while the animation was rendering. What happened was, everytime we rendered, the textures wouldn't appear. Only a few textures appeared in the final rendered movie but the rest appear to be missing. I'm not sure why the textures didn't appear, it could be that some files were corrupted or maybe renamed and maya was getting confused. We made the best of what we had and used that as our final film.
