texture problem!

i created a texture map from an unseemd mesh. the texture looks awesome but when i applied it to the object. the texture appeared on the inside :S. does anyone know a quick way to apply the texture to the side that matters? (outside) its a complex mesh and i dont want to redo it all.

textures will apear on the face side that the normals are pointing out , your normals must be facing inwards instead of out so you need to flip the normals by selecting all the faces in edit mode and pressing w and choose flip normals from list or do ctrl+n to recalculate normals.
