Include the header atlimage.h (your project must use ATL or MFC) and use the class CImage: it provide an easy way to load, save, render and access pixels on images from/to various formats, like bmp, jpeg, png, etc.
Here you can find the documentation about the class: CImage Class(ATL/MFC)[^]

Another option (as CImage is a GDI+ wrapper) is using directly GDI+.
