The images in question are JPEGs and I've gotten them down to a smaller size (30kb). The wordpress site in question is responsive and this issue on happens when I'm using mobile network to load the site. Wirelessly, it has no issues but on 3G/4G, images loaded randomly, some are corrupted, images swap places, so all css and js seems messed up. I'm using W3 cache to enhance the speed, but nothing is helping. Some images are half grey, black and look corrupted sometimes. This only happens on iOS devices with safari browser.
Anyone else faced the same issue? On desktop being wired, wireless, I've never had this issue.
Not sure if it has to do with with database or overall site performance of the server. Any help is greatly appreciated.
