Arrows are not in the vertical center of the image

Hi,

The arrows are not in the vertical center of the image, but in the vertical center of the image+caption. I'd fix that.

Hi @dijkermans, thanks for opening the issue. Yes, this is definitely a bug. At the moment we are heads down with other projects but we would always welcome a PR for this 🙌
