i'm using SDL to create my opengl context but i wonder can i still use SDL's surface blitting too while using opengl. I ask because i may want to use SDL_mappy in the future or another SDL library

You can't blit to the screen surface. However, you can create your own buffer surface, use it with SDL_mappy and then upload the contents to an OpenGL texture.

You need to use Textures to draw images with opengl (if its a 2D game you will use GL_TEXTURE_2D). You will use glTexImage2D to create the texture from the surface pixels.
