title: image loading error with suffix '.Jpg'
body: <p>I encountered an image loading error. Error messages were as follows:</p>
  
  <blockquote>
    <p>PAC Fetch failed with error [NSURLErrorDomain:-1004] []
    nw_proxy_resolver_create_parsed_array PAC evaluation error:
    NSURLErrorDomain: -1004</p>
  </blockquote>
  
  <p>Found that URLs of those images had an suffix <code>.Jpg</code> or other uncommon things, which correct loaded on Android.
  I guess the problem is the wrong suffix, but not sure. I can't understand the meaning of those error msgs. Could anybody help me?</p>
