how to develop texture with mipmaping levels and Method is streamed

I used photoshop and GIMP softwares to create textures. using these softwares I am not able to create textures with mip levels and mip generation setting to “Texture Group” and Method =Streamed.

Please help me to create texture with below qualities.

  1. Mip Levels
  2. Mip generation setting to “Texture Group”
  3. Texture Method = Streamed (means Never stream=false)
