Shortcode Owl Carousel Image Descriptions

Can’t figure out how to add image descriptions/names…does anybody know?

You mean text over the image? The docs have a sample:

[owl-carousel items=2 margin=10 loop=true]
<div style="background: url({{ page.media['image-1.jpg'].url }}) 50% 50%;background-size: cover;color:#fff;">
  <h2>This is panel 1</h2>
  <p>foo</p>
</div>
<div style="background: url({{ page.media['image-2.jpg'].url }}) 50% 50%;background-size: cover;color:#fff;">
  <h2>This is panel 2</h2>
  <p>foo</p>
</div>
<div style="background: url({{ page.media['image-3.jpg'].url }}) 50% 50%;background-size: cover;color:#fff;">
  <h2>This is panel 3</h2>
  <p>foo</p>
</div>
[/owl-carousel]

I think the CSS provided with owl-carousel plugin should handle this. If you want other styling, you will need to add it.
