    Problem Someone please help!

    Hey, new to the forum and new to openGL, so he goes my problem.

    I have written some code which loads in a few textures and displays one as a background image, I wish to then overlay this image with another image. In a crude attempt at animation i want to load in several images to create basic texture animation. This i can do HOWEVER the problem is how do i keep my background image whilst playing the animation over the top of it? I'm confused with regards to buffers and matrix pushing and popping. I hope someone can help or at least point me in the right direction, thanks!

    Trying to give a high level view :

    for each frame :
    - glClear color(+depth if needed)
    - draw static background image
    - draw current overlay image
    - swapbuffers

    This should be enough.
