# Blurry full-size image on mobile

 * Hello! So I have this real estate website that uses lightboxes on slider images.
   When you tap on the featured image in the slider, you can tap it and it opens
   the image lightbox in which you can zoom in on.
 * However, the image is cropped to the screen size instead of being full size, 
   making that zooming in reveals nothing more; [it just shows a blurry mess](https://i.gyazo.com/975ffbd66754ec056dd333227fbedd01.jpg).
 * The only workaround I have found to this was to exclude the listing pages from
   optimisation, but given that each listing has a lot of photos and that our server
   is not very powerful, this would add several seconds to the page loading.
 * What should I do?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fblurry-full-size-image-on-mobile%2Fpage%2F2%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Apologies for the super late reply.
 * I have installed your plugin in my staging environment. If I understand correctly,
   I need to set the height and width of my image to “auto” for this to work?
 * Otherwise, it doesn’t seem to do anything. My zoomable images are still “crusty”.
   
   If you’d like, I can give you access to my staging environment so you can freely
   explore the issue that’s on my website.
