No worries, most people probably don't realise slider and slideshow are different things.

I don't know if it's the only way to do it, but when I was trying to find the answer to that, I searched for a while, couldn't find an answer and came up with this solution. (If you do find another way later, please let me know)

I've been using it for a while, in two main places: ""
 * Floating portrait-sized sliders to the side of an article without wasting extra space

""
 * Enlarging the height of portrait-sized images in a page-width slider.

edit:

In case it's not obvious, how it works is that galleries are always set to the landscape dimensions, and the height cannot be set independently from the width, so instead, we set the width to be wide enough to get the height we want, then override the width in order to trim the blank space around the edges.

You sometimes need to play around with previews for a while in order to find the widths value to give you the height you really want, but it beats not being able to do it at all.
