Need to add an image to the gallery, can't install a large image?

Question

Ruby on Rails

For a more detailed review of the goods, I added a gallery found on the Internet, its difference from others is that the img tag contains the data-image parameter, which contains a link to a large image, here is the gallery itself:

as you can see, the small image has loaded, but the large one has not, here given code

Using the image tag, I was able to add a thumbnail image, but for a large one it doesn’t work, because there is no data-image parameter in the img tag. Is there a solution to this problem, or is it better to find a simpler gallery?

Answer 1

<%= image_tag small_image_url, data: { image: big_image_url } %>
