Figcaption is hidden when the screenshot image height is bigger than 600px

[Mirucon]

When I have a screenshot image that height is bigger than 600px, the bottom part of image is cut off, and even the caption is hidden.

In 5938:

Plugin Directory: Make sure tall screenshots fit into the slider, which is limited to 600px in height.

Fixes #3142.

wouldn't it be simpler to simply remove the css styling:

.plugin-screenshots .image-gallery-slides {
    max-height: 600px;
}

and let the screenshot image height vary? I think its easier to let users add any ratios (width/height) of screenshots rather than constrain them to landscape ratios.
