You need to load your image into an OpenGL texture and then display the texture at the vertices you specify. Note that the texture width and height needs to be a power-of-2, so you’ll have to pad the margins and adjust your vertices to get the correct placement if the image is not power-of-2. Apple has a great example of this in the GLSprite sample code.
