title: Problems loading images on 3G connections
body: <p>I've been asked to help diagnose issues with a <a href="http://www.signatureannualawards.org.uk" rel="nofollow">website</a> which uses stellar.js to create a parallax type effect that continues to work on mobile devices. </p>
  
  <p>While connected to the office wifi the website loads all images and performs normally. On 4G the website is also fine.</p>
  
  <p>However on 3G the images fail to load on mobile devices (iPad Air 2, Galaxy S6 used to test). The kicker is, the 3G connection at 16Mb/s is four times faster than the very basic office wifi which reaches just 4Mb/s. </p>
  
  <p>The images themselves are seven jpg's which are between 100 and 157 KB in size, most closer to 100 with the total of all seven being 792KB.</p>
  
  <p>My initial suspicion was connection speed or device not being able to handle the images, but after resizing them to be much smaller and finding that they work just fine over the offices much slower wifi connection this sort of rules speed/device power out.</p>
  
  <p>So currently I am at a loss. Any suggestions for how to proceed diagnosing the issue or potential solutions?</p>
