It's really difficult to tell from a photo.
Most djembes made in Ghana are made of Tweneboa, a very pale and soft wood, rather poorly suited to making djembes. The drum in the pictures you posted doesn't look like it's made of Tweneboa. But, I'm wondering whether that drum was stained. Something about the coloration doesn't ring quite true with me.
What's the weight of that drum? That will tell you something about the kind of wood it might be made out of.
