I bet it is him - the sticker says Dark Arts at the bottom - and Moody is the teacher of Dark Arts. I bet they will have the eye patch on most of the time (since it would be a continuous digital effect to have the magical eye all the time - too expensive and time consuming) and just have certain creepy instances where they zoom in and Moody lifts the eye patch to reveal the magical eye underneath. Imagine the final scene at King's Cross station where Moody intimidates Vernon Dursley by showing him his eye. I think that would work well.

Also, his hair is supposed to be long and gray - so that fits the picture.
