Scaling a mounted image

I have a mounted axe that is way too big. I tried scaling it in the ShapeBaseImageData datablock and it dosent do anything (unless im trying to scale it down the wrong way).

datablock ShapeBaseImageData( CleaverImage )
{
...
scale = ".002 .002 .002";
....
}

The rotation works that I set in this datablock but for some reason the scaling isnt doing anything. Any input or thoughts on what im doing wrong would help. Thanks
