I have recently been trying to learn C++, and I have some of the basics down, but I cannot for the life of me find out how to open an image. I am trying to make a side-scroller, and I just can't figure out how to do it, but for now, I just want to open an image. Preferably in a simple way. FYI, I'm using Visual Studio.

If you are going to concentrate on programming strictly for Windows there is DirectX:

For (relatively) simple picture and text manipulation there is C++ class-based GDI+:

Windows GDI and GDI+ have been superseded by Direct2D:
