Draw a Simple Picture with OpenGL ES

[iphoneboon]

First of all I'm sorry for my bad englisch.
I want to draw a simple picture on iphone with opengl. I have a programm that load a picture from the storage and converts the image into a texture.
Then it draw the picture. My problem ist that the image on the screen hat a bad quality. I want to draw the image directly with glBitmap, but this function is not include in ES, or? So how can i draw a picture directly on the screen.
The draw process should be fast, because the picture is dynamic.

Thx for every advice or help.
