Improve slideshow appearance

[cosmiccoincidence]

Currently, the slideshow looks and performs a little wonky...

The description bar for the images disappears if there is no description which sounds nice in theory but in practice, this shifts the image thumbnails (that are directly beneath it) down and back up as you pass through images with and without descriptions (as a result it also shift the control arrows for these thumbnails which is annoying). This looks and feels bad.

An easy fix for this may be to just move the thumbnails above the primary image so there is not part of the slideshow that is beneath the image description. A more proper solution is wanted tho because although no part of the slideshow itself will be getting shifted up/down, the entire rest of the page beneath the slideshow still does, and it just doesn't look/feel good.

assigned it to me, please. I can fix the thumbnail issue as well as smooth transition and responsive design for this.
