Vertical align the slideshow

Hi

We are trying to vertically centralise the images because we have different width images.

Here is a link to an example slideshow.

As you can see the some images fill the space, which is what we want and with some there is a gap left at the bottom of the image. We need the long narrow images to be vertically centralised as per the squarer images.

Can anyone help with this?

Thanks 🙂
