1) Read it using some apropriate function (e.g. libjpeg for jpg files).
2) Upload it as a texture
3) Instead of clearing the color buffer, draw a quad with the texture which covers the entire viewport
This method is insensitive to screen/window resolution since the texture will be sceled to fit the viewport (use GL_LINEAR filtering).
IŽll try that.
