I found the problem. It was the chrome cache that not updated images . I cleared the cache and it worked. But in IE11 gives a strange error ” Internet Server Error 500″.

I’ll do some testing here.

Or you can use proxy.
Here is a list.

I tried and it worked.

You can also use the extension google chrome “Data Compression Proxy”, it will set up an automatic proxy. It worked well here,

See you.
