texture Normal Mapping problem

hello people,

i tried textureing an object with two textures , one as a texture and mapping and the other for mapping only and it looked good but when i changed the view i found weird shapes on the texture

what are these??? and how can i remove them?

It’s wrong section for that kind of question so don’t expect many replies.
You should post it in Support/Texturing&Lighting section :

And it’d be better to provide .blend file or more pics with texture(s) setup.
