Beginning graphics

I want to begin programming 2d graphics. The only graphics I've ever dabbled in were java applets (which barely count). I've practiced java for a year and a half, but I know enough c++ to get by.

My question: How does one go about getting into programming 2d graphics?

Anyone recommending SDL for anything at all is a moron or a troll. Anyone recommending OpenGL for 2D is a troll.
Allegro is great in that it's easy to get into and basically does everything you want it to. Regardless of its suitability for serious game programming nowadays (I happen to think that it's very suitable, but idiots could disagree), it's at least a great starting point.
