tangent maps

how do I render a image properly using a tangent space map like this





I have tried mapping it to my bump map and using right and left handed tangents but both give me weird results

normally I just map to bump map and hit tangent space normal's and I get decent results but not with this one

I am guessing I will have to use some type of complex shader set up but I could not find a tut for one on line

The map looks like its object space normals or something. The problem is, if the model needs to deform the object space normals won't look good anymore. You can convert to tangent space normals, pretty easily too as far as I know, some googling should put you on the right track.
