The method for solving normal Rubik's Cubes follows the same concept for solving pictured Rubik's Cubes. The only difference, is that you need to use some intuition to make sure that the Center pieces are positioned the correct way. I would just suggest solving it, with the surrounding pictures correct, and not worrying too much on the centers.. You will then realize that the center pieces will usually be wrong. Think about how you will correctly position the center pieces, then resolve it (hopefully you would have done it correctly).
That's just how I solved them...
There might be another method particularly for pictured Cubes, but I don't actually know what that would be.
