When you set up your texture use

glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTE R,GL_LINEAR_MIPMAP_LINEAR);
glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTE R,GL_LINEAR_MIPMAP_LINEAR);

and then set up the correct mipmap image.

See starting on page 338 of the Red book second edition-"Multiple Levels of Detail" is the section name.
