texture not working in game?

hi, i just made a game and i textured some stuff with uv image editor, but when i start the game the textures arent there. can anyone help me?

Have you given your model a material and added your UV image to this material ?

I dont think so, I just unwrap a face and then in the uv image editor I open a image and doneā€¦ it appears in the texture paint mode but not in game.

can anyone explain yo me how u do that?:o
