C ++ OpenGL texture mapping

Question

I read about this, including Nehe, and here for solutions, but I cannot find a specific answer.

I am trying to upload a photo called stars.jpg. I want to make this my scene background by matching it using uv coordinates, doing it with

glBegin(GL_QUADS);
glTexCoord2f(0,0);
glVertex2f(0,0);

However, I'm just very confused about how to load the actual textures, all the calls for

glActiveTexture();
glEnable(GL_TEXTURE_2d);
glBindTexture(GL_TEXTURE);

Everything that they do confuse me, what does it all mean / do, and in what order, I suppose, to insert them, to get stars.jpg, to be my background?
