I've seen this question before, but the answer is evading me. There are four images on the front-page of the site http://miraishii.com. The top image, in the section displays fine, but the three within the second section don't. They are assigned images with id's gal-1, gal-2, gal-3.
The images display fine in desktop browsers, but neither iOS Safari nor iOS chrome will display the background-images. I'm using the Safari inspector to view the site, the images seem to be loading, but not displaying.
