title: Woocommerce product slider doesn't show second image
body: <p>this is my first question on Stackoverflow.</p>
  <p>I have a webshop for my clothing company, but I have a issue with my product slider on the product page. I added a second image, the images to slide to the second image works perfectly fine, but he won't show the second image. I found out that the images are under each other, in stead of next to each other. Does someone knows how to fix this? I have tried a lot of things for a couple of hours...</p>
  <p>Link to the product with a slider: <a href="https://freezing-clothing.nl/product/freezing-stickers/" rel="nofollow noreferrer">https://freezing-clothing.nl/product/freezing-stickers/</a></p>
  <p>Kind regards,</p>
