Am I seeing an Orange side, but a Blue/Red piece? So, there's a Blue/Orange on the back/right side?
I won't provide you an algorithm, but if you've got basic understanding of moves you can figure it out.
Holding the cube as pictured, you'll need to turn the orange face counter clockwise, then bump the blue/white piece out (left) to the middle layer, then return the orange face (clockwise). Rotate the top as needed and move the blue/white piece to it's correct spot (occupied by the blue/red). By doing that, you'll bump the blue/red piece out.
Rotate again as needed and then move the blue/red to it's correct spot (occupied by the blue/orange). That bumps the blue/orange out. Now all you have to do is put that one piece away and if you did it right, without unnecessary steps, you'll be done.
