Texturing

Applying textures in OpenGL involves the following steps:

Enable texturing 
glEnable(GL_TEXTURE_2D);
 
Define a texture 
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, IMAGE_WIDTH, IMAGE_HEIGHT,
             0, GL_RGB, GL_UNSIGNED_BYTE, textureImage);
 
Assigned texture coordinates 
glTexCoord2i(0,0);
glVertex3f(-1.0, -1.0, 0.0);
glTexCoord2i(1,0);
glVertex3f(1.0, -1.0, 0.0);
