Lightbox slider blurry image

Hi
As you can see in the Read-Only link, all the images are of good quality, but on the live site, they appear really blurry. I’m not sure why this is happening or how to fix it. Can you help?

Thank you!

I got the solution. Webflow’s system automatically compresses images too much for the lightbox feature, so we need do "disable responsiveness’'.
