Haven't figured this one out.

Is there a way to tile a texture? For example, if I were to use a pic of a marble tile, (complete with grout), and tile it across the floor (using a sign, or whatever).

I've had to create huge blocks of already tiled textures... and my zaby now maxes out my memory. With tiling, I could just set the small texture, and let the client do the work (and save RAM).
