What's the difference between normal textures, and bumpmap textures?

Bumpmaps add more texture to textures, if that makes sense.
Wrinkles, shading, bumps and so on all look more realistic and the textures have added depth to them.

Bumpmap makes it look more 3D on the main texture

Rekd sent me this pic when he made my bumpmap textures, it's side-by-side comparison
of my headtexture with/without bumpmaps (left is with)

Ah ty, closing thread now.
