Hmm, the pictures are not showing up, it seems like you're not allowed to link them from that host.

If you're talking about Maya and the difference between High Quality display of normal maps and the renderer, you have to use Mental Ray to render, and make sure the "Use Maya Derivatives" checkbox is enabled in the Mental Ray advanced settings.

This is a bit of a guess because I can't see your images either but it may be to do with the UV winding order. Try checking in "Tangent Space" rollout in the shape node tab for your object and make sure "UV Winding Order" is set to "Detect".
