I can not tell you exactly how the paths work. But I would point out that 
if you want to work with relative paths be sure to pre-pend ./ to the path 
in the tile index. For example, if you have a DATA directory and you have 
an IMAGE directory below it, in your tile index you should specify:
     ./IMAGE/filename.tif
not simply:
     IMAGE/filename.tif
